CFLP,CFLP,"Recently the city revisited its pickup plan: decide which transfer stations should be in operation and for every block pick a single active station that will collect its rubbish. No station can be given more than it can deal with, and every block must be assigned to exactly one open station. What counts as a better plan is a lower overall expense — add up the startup cost of every station that gets switched on and the hauling cost for every block’s trip to its station; the total should be as small as possible. The exact figures and options are shown underneath.

One more thing — when you send back the plan, please use this simple JSON shape so it's easy to check:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_station>, <chosen_open_station>, ...]
  }
}

""selected"" is where you list the transfer stations you decide to turn on. ""assignments"" is a list (in block order) showing which open station each block is assigned to. Think of it like filling out a form: a short list of active sites and then, for every block, the one chosen station.

This is just a sketch of the expected shape — not the actual answer.

Please use the exact identifiers from the instance input, with no renaming and no invented labels. For example:
Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [400.0, 400.0,

CFLP,CFLP,"Recently the team sat down with a map of stores and candidate depots and boiled the task down: open some depots, and send each store’s whole order to a single open depot (no partial shipments, all stores covered), while not overloading any depot beyond its capacity. The way to judge plans is by their total cost — just add up depot activation fees and the delivery costs to the stores — and pick the smallest. The concrete details will be shown below.

There are 6 depots and 17 stores in this instance.

And just so we're on the same page about the output format, please return your plan using this simple JSON layout below — it’s just the shape I expect, nothing fancy.

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

Think of ""selected"" as the list of depots you decide to open, and ""assignments"" as, for each store (in the same order they appear in the instance), which open depot will handle that store. Easy, informal — like filling out a short form.

This JSON is only a sketch of the expected shape, not the actual answer. Also, please use the exact identifiers from the instance input — do not rename them or invent new labels. For example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

Use these figures to choose which kitchens to staff and assign every one of the 16 schools without exceeding any kitchen's capacity, minimizing total cost.

Also, when you hand me a plan, please use this little JSON layout so it's quick to check and compare plans — nothing fancy, just a predictable shape.

{
  ""solution"": {
    ""selected"": [<kitchen_to_staff>, <kitchen_to_staff>, ...],
    ""assignments"": [<kitchen_serving_school>, <kitchen_serving_school>, ...]
  }
}

""selected"" is where you list the kitchens you plan to staff (one entry per kitchen). ""assignments"" is where you list, for each school in the order they appear in the instance, the single staffed kitchen that will serve it. Think of the JSON as a simple form: the first array says which kitchens are open, the second array says who serves which school. It's just a sketch of the expected shape — not the final plan.

Please be sure to use the exact identifiers from the instance input when you fill this in — do not rename them or invent new labels. Valid identifiers look like plain numbers such as ""1"" or ""23"", single capital letters like ""A"" or ""B"", or a capital letter followed by digits like ""A1"" or ""X7"".","{'opening_costs': [243.0,

CFLP,CFLP,"Imagine running the hospital network for a region and having to pick a handful of outpatient clinics to operate while assigning every neighborhood’s patients to one of them. Every clinic you flip on carries a fixed opening cost, each neighborhood has a travel price to each clinic, and every clinic can only accept so many patients. What makes one choice better than another is the total price tag — add the opening costs of all chosen clinics to the travel costs for all neighborhoods to calculate it, and the aim is to keep that total as small as possible. No neighborhood can be left unassigned or split between clinics, and no clinic may exceed its capacity. The full list of clinics, capacities and travel costs appears below.

There are 8 clinics and 18 neighborhoods in this instance.

Also, when you send back the actual choices, please use this little JSON layout so it's easy to read and automatic tools can pick it up:

{
  ""solution"": {
    ""selected"": [<clinic_to_open>, <clinic_to_open>, ...],
    ""assignments"": [<assigned_open_clinic>, <assigned_open_clinic>, ...]
  }
}

Think of ""selected"" as the list of clinics you decide to flip on, and ""assignments"" as, for each neighborhood in the same order they were given, the clinic you routed that neighborhood's patients to. Super casual: it's just a form—one list of open clinics and one list saying who goes where.

This is just a sketch of the expected shape, not the actual answer. Please make sure all identifiers you put in there match the instance input exactly — no renaming, no invented labels.

- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"I’m running the food area for a neighborhood festival and need to decide which food stalls to actually set up and which vendor crowds to point to each stall. Each stall costs money to put up and can only serve so many people, and every time a vendor’s customer area is assigned to a stall there’s a serving cost based on distance or effort. The plan has to send each vendor’s customer area to exactly one of the stalls that get set up, make sure no stall serves more people than it can handle, and keep the total bill — the sum of all stall setup costs plus all those serving/distance costs — as low as possible. The specific stall options, costs, capacities, and vendor customer areas are listed below.

I have 7 candidate stalls and 17 vendor areas to consider.
For stall F1 I would pay 600.0 to set it up and it can serve up to 700.0 people.
For stall F2 I would pay 600.0 to set it up and it can serve up to 700.0 people.
For stall F3 I would pay 600.0 to set it up and it can serve up to 700.0 people.

I'll pick which stalls to open and assign every vendor area so the sum of stall setup costs and serving costs is as low as possible.

Oh, and one more thing — when you send the plan back, please put it in this little JSON sketch so I can read it programmatically. Just follow the layout below; it's just a simple form that says which stalls to open and which stall each vendor is sent to.

{
  ""solution"": {
    ""selected"": [<stall_to_open>, <stall_to_open>, ...],
    ""assignments"": [<chosen_open_stall>, <chosen_open_stall>, ...]
  }
}

Think of ""selected"" as the list of stall locations you decide to set up, and ""assignments"" as, for each vendor/customer area in the order they were given, the stall you point them to. Super casual — it's just a template of the shape I need, not the final answer itself.

Please make sure to use the exact identifiers from the instance input — don’t rename them or invent new labels. 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"We’ve got a handful of data centers that can be spun up and a bunch of applications that need service; the job is to pick which centers to activate and then point each app’s traffic to a single active center. Each center costs money to bring online and has a hard bandwidth ceiling, and connecting an app to a center also costs something. A better plan is simply the cheaper one: total expense equals the sum of the centers’ startup charges plus all the routing fees, provided every app is covered by exactly one center and no center’s bandwidth limit is exceeded. The exact numbers and limits follow below.

Also, when you send the plan back, please use this simple JSON layout so it's easy to parse — just a quick sketch of the shape we expect:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

Pretty straightforward: ""selected"" is the list of data centers you decide to spin up, and ""assignments"" lists, in the same order as the applications were given, which spun-up center each app is pointed to. Think of it like filling out a short form — which centers are active, and which active center each app uses.

This JSON is just the shape I want to receive, not the actual answer. Please make sure to use the exact identifiers from the instance input — do not rename them or invent new labels. Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [300.0, 300.0,

Oh, and when you give the final pick and assignments, just stick to this simple JSON shape so it's easy to read and check:

{
  ""solution"": {
    ""selected"": [<van_to_operate>, <van_to_operate>, ...],
    ""assignments"": [<operating_van_for_neighborhood>, <operating_van_for_neighborhood>, ...]
  }
}

""selected"" is the list of vans you'll run (one identifier per van). ""assignments"" lists, in neighborhood order, which of those running vans is assigned to serve each neighborhood. Think of it like filling out a short form: pick the vans, then write next to each neighborhood which picked van will visit it.

This JSON is just a sketch of the expected shape — not the actual answer. Please be sure to use the exact identifiers from the instance input — don't rename them or invent new labels.

- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"I’m the emergency planner trying to set up a handful of supply hubs after a disaster, and the job is to pick which hubs to open and then link every relief site to one of those open hubs. Each hub costs money to establish and can only hold so much inventory, and sending supplies from a hub to a site adds shipping costs. The goal is to choose hubs and assignments so the total bill — the hubs’ setup costs plus all shipment costs — is as small as possible, while making sure every relief site is assigned to exactly one open hub and no hub’s stock limit is exceeded. The specific sites, hub options, capacities, and costs are shown below.

I can consider 8 candidate hubs and must serve 16 relief sites.
Hub F1 would cost 600.0 to open, and I can stock up to 700.0 units there.
Hub F2 would cost 600.0 to open, and I can stock up to 700.0 units there.
Hub F3 would cost 600.0 to open, and I can stock up to 700.0 units there.
Hub F4 would cost 600.0 to open, and I can stock up to 700.0 units there.
Hub F5 would cost 600.0 to open, and I can stock up to 700.0 units there.
Hub F6 would cost 600.0 to open, and I can stock up to 700.0 units there.
Hub F7 would cost 600.0 to open, and I can stock up to 700.0 units there.
Hub F8 would cost 600.0 to open, and I can stock up to 700.0 units there.
Relief site 0 needs 28.0 units that I must assign to one open hub.
Relief site 1 needs 23.0 units that I must assign to one open hub.
Relief site 2 needs 28.0 units that I must assign to one open hub.
Relief site 3 needs 18.0 units that I must assign to one open hub.
Relief site 4 needs 12.0 units that I must assign to one open hub.
Relief site 5 needs 20.0 units that I must assign to one open hub.
Relief site 6 needs 29.0 units that I must assign to one open hub.
Relief site 7 needs 22.0 units that I must assign to one open hub.
Relief site 8 needs 18.0 units that I must assign to one open hub.
Relief site 9 needs 27.0 units that I must assign to one open hub.
Relief site 10 needs 23.0 units that I must assign to one open hub.
Relief site 11 needs 21.0 units that I must assign to one open hub.
Relief site 12 needs 11.0 units that I must assign to one open hub.

I'll use this information to decide which hubs to open and how to assign every site.

Also, for the answer please use this simple JSON shape so it's easy to plug into my planner:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

""selected"" is the list of hubs you decide to open. ""assignments"" lists, for each relief site (in the same order the instance gives them), which open hub that site is assigned to. Think of it like a short form: which hubs to set up, and which hub each site will get supplies from.

This is just the expected shape of the reply — a sketch, not the actual filled-in solution. Please make sure to use the exact identifiers from the instance input; do not rename or invent new labels.

Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [600.0, 600.0,

CFLP,CFLP,"We manage local solar install crews and need to figure out which teams to switch on and which team will do each installation. Each team you turn on charges an activation fee and can only take on a certain amount of work; sending a team to a customer also costs travel and the actual service time. What makes one plan better than another is the final tab: add up the charges for every team we activated plus every travel and service cost for each assigned customer, and choose the assignment that produces the lowest total, while making sure every customer is assigned to one active team and no team’s workload goes over its limit. The exact team fees, capacities, and customer requests are shown below.

When you send the plan back, please use this simple JSON layout so it's easy to read and plug into our system:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_site>, <chosen_site>, ...]
  }
}

Think of ""selected"" as the list of crews/teams you switched on (the ones we'll pay an activation fee for), and ""assignments"" as which switched-on crew will handle each customer in the same order the customers were given. This is just the shape I expect — a sketch, not the final numbers.

Please use the exact identifiers from the instance input — do not rename them or invent new ones. Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [600.0, 600.0,

CFLP,CFLP,"Picture a rollout where each potential tower has a startup cost and a limit on how many users it can serve, and each service area has a certain number of users. The job is to decide which towers to commission and to assign each service area to exactly one of the commissioned towers — no area is left unassigned or assigned twice, and no tower is overloaded. The best plan is the one with the smallest overall bill: add together the commissioning costs for all commissioned towers and the connection penalties for each area’s assignment, and keep that sum as low as possible. The actual numbers for costs, capacities, and connection penalties are shown below.

There are 7 towers and 15 areas in this instance.

When you give the plan, just use a simple JSON layout like this so it's easy to read and parse — nothing fancy, just which sites you open and where each area gets assigned:

{
  ""solution"": {
    ""selected"": [<tower_to_open>, <tower_to_open>, ...],
    ""assignments"": [<chosen_open_tower>, <chosen_open_tower>, ...]
  }
}

""selected"" is the list of towers you decide to commission, and ""assignments"" says, for each service area in the order given by the instance, which commissioned tower it will use. Think of it like filling out a short form: a list of opened towers, and a list that points each area to one of those towers.

This JSON is just a sketch of the shape I expect — not the final answer itself. Please make sure to use the exact identifiers from the instance input (do not rename or invent IDs). 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"Recently the health team put together a list of possible pop-up clinics and all the neighborhoods that need coverage; the task now is choosing which clinics to run and which single clinic each neighborhood will use. Each clinic has a daily throughput cap and an opening cost, and each neighborhood-to-clinic pairing carries a transport cost. The best setup keeps the combined expense down — sum the opening costs for clinics that get opened plus every neighborhood’s travel cost — and it must assign every neighborhood to one open clinic without exceeding any clinic’s daily capacity.

Also, when you’re ready to hand over a proposed setup, just use a tiny JSON snippet like this so it’s easy to parse:

{
  ""solution"": {
    ""selected"": [<clinic_to_open>, <clinic_to_open>, ...],
    ""assignments"": [<neighborhood_chosen_clinic>, <neighborhood_chosen_clinic>, ...]
  }
}

Pretty simple: ""selected"" is the list of clinic sites you plan to open, and ""assignments"" lists, in the same order as the neighborhoods in the instance, which open clinic each neighborhood will use. Think of it like filling out a form — which clinics are on, and for each neighborhood which clinic they go to.

This JSON is just the expected shape (a sketch), not the final answer.

Please be sure to use the exact identifiers from the input files — don’t rename or invent new labels. 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"Many event planners know the drill: pick which mobile kitchens to bring and decide which kitchen will handle each event. Every kitchen has a rental price and a maximum number of meals it can do; every event needs all its meals from one kitchen only. The decision that works is the one where all events are assigned (no splits), no kitchen is overloaded, and the total expense — the sum of trailer deployment costs plus each event’s delivery fee — is kept as low as possible. The full set of trailer capacities, deployment fees, and event meal counts appears below.

There are 8 trailers and 16 events in this instance.

One more thing — to keep things machine-friendly, please lay out the final decision in a tiny JSON sketch like this:

{
  ""solution"": {
    ""selected"": [<kitchen_to_rent>, <kitchen_to_rent>, ...],
    ""assignments"": [<chosen_kitchen_for_event>, <chosen_kitchen_for_event>, ...]
  }
}

Think of ""selected"" as the list of mobile kitchens you'll rent, and ""assignments"" as, for each event (in the same order the events were given), which rented kitchen will handle it. Super casual form: which kitchens you bring, and who feeds which event.

This JSON is just the shape I expect — a sketch, not the actual values. Also, please use the exact identifiers from the instance input when filling those placeholders: do not rename them or invent new labels. Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [300.0, 300.0,

CFLP,CFLP,"The planning team has to decide which candidate docking stations to activate and then assign each commuter zone to exactly one activated station, taking care that stations aren’t asked to serve more riders than their dock counts allow. Activating a station charges a cost, and each assignment carries a redistribution or travel cost; the total cost of any configuration is simply the sum of the activation costs for chosen stations plus all assignment costs, and the aim is to keep that combined total as low as possible. Every commuter zone needs a single assigned station (no omissions or duplicates), and station capacities must not be exceeded. The detailed instance information is provided below.

You can just reply with the results in a simple JSON shape — nothing fancy. Here's the layout to follow:

{
  ""solution"": {
    ""selected"": [<station_to_open>, <station_to_open>, ...],
    ""assignments"": [<assigned_station>, <assigned_station>, ...]
  }
}

""selected"" is where you list the station identifiers you choose to activate, and ""assignments"" is a list that (in the same order as the commuter zones were given in the instance) names the single activated station each zone is assigned to. Think of it like filling out a short form: which stations are turned on, and which station each zone uses.

This JSON is just a sketch of the shape I expect — not the actual solution values.

Please use the exact identifiers from the instance input — do not rename them or invent new labels.
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"We’ve got a bunch of farms and a shortlist of packing facilities; the job is to pick which facilities to operate and route each farm’s harvest to one of the open ones. Each facility has a running cost and a hard limit on how much it can process, and moving produce from farm to facility incurs transport charges. The winning plan is the one with the smallest overall cost — that’s just the sum of all facility opening costs plus all transport charges. Every farm’s output has to go to exactly one operating facility, and no facility can be overloaded beyond its limit. The exact facilities, capacities, and costs are listed below.

Oh, and when you send the plan back, keep it in a tiny, predictable JSON shape so it's easy to read. Something like this:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

""selected"" is just the list of packing sites you decide to run, and ""assignments"" is a list (in the same order as the farms were given) saying which open site each farm ships to. Super casual — think of it like filling out a short form, not a technical report.

This JSON is only a sketch of the expected shape, not the actual answer. Please use the exact identifiers from the instance input — do not rename or invent labels. 

Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [400.0, 400.0,

CFLP,CFLP,"Many people organizing artisan fairs face this: deciding which vendor booths to rent and how to assign each maker to a single rented spot. Booths cost money and have limited display space, and assigning a maker to a booth usually incurs a setup/transfer charge. A smarter layout is the one that costs the least overall — add together the booth rents and all assignment/setup charges to get the final cost — while making sure every maker gets one rented booth and no booth’s space limit is broken. The specific booth fees, capacities, and maker requirements come next below.

There are 7 booths and 16 makers in this instance.

Oh, and when you send the solution back, just use this little JSON layout so it's easy to check:

{
  ""solution"": {
    ""selected"": [<booth_to_rent>, <booth_to_rent>, ...],
    ""assignments"": [<rented_booth_for_maker>, <rented_booth_for_maker>, ...]
  }
}

""selected"" is where you list the booths you're renting. ""assignments"" is one entry per maker, saying which rented booth that maker gets (use the same order the instance lists the makers). This is just a sketch of the shape I expect, not the actual answer — fill in the real identifiers from the instance.

Please make sure you use each identifier exactly as it appears in the instance input — no renaming and no new labels. 

- For example: ""Valid identifiers look like plain numbers such as ""1"" or ""23"", single capital letters like ""A"" or ""B"", or a capital letter followed by digits like ""A1"" or ""X7"".""","{'opening_costs': [300.0, 300.0, 300.0, 300.0, 300.0, 300.0, 300.0], 'capacities': [500.0, 500.0, 500.0, 500.0, 500.0, 500.0, 500.0], 'connection_costs': [[570.0, 83.0, 107.0, 46.0, 495.0,

CFLP,CFLP,"At the coordination office the question is straightforward: which staging areas should be staffed, and which staffed area should handle each beneficiary community? Staffing each area costs money and comes with a limit on how many people it can serve; moving aid from a staffed area to a community also costs something. Each community must be assigned to one staffed area only, and no staffed area can be assigned more demand than it can support. The plan that’s “better” is the one with the lowest total expense — add together the staffing costs for all staffed areas used and the distribution costs for every community assignment — and choose the arrangement with the smallest sum. The concrete details are given below.

Also, when you send the plan back, please follow this simple JSON layout so it's easy to parse and check:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

Think of ""selected"" as the list of staging areas you'll staff, and ""assignments"" as which staffed area handles each beneficiary community (listed in the same order as the communities in the instance). This JSON is just a sketch of the shape I need — not the final answer itself.

Please make sure you use the exact identifiers from the instance input, without renaming or inventing new labels. 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"There’s a juggling act in the warehouse world: a bookstore chain has several candidate warehouses, each with a set capacity and a fixed fee to open, and a bunch of shops that all need restocking. The job is to pick which warehouses to open and assign every shop to one of the opened warehouses. Better choices are the ones that save money overall — add up the opened warehouses’ fixed fees and all the shipping charges to see the total — but a warehouse can’t be given more orders than its capacity, and every shop must be assigned to exactly one opened warehouse. The detailed figures are shown below.

They list 9 candidate warehouses and 19 shops.
Candidate warehouse F1 has opening cost 400.0 and capacity 1382.0.

Use these figures to pick which warehouses to open and assign every shop while respecting capacities and minimizing total opening plus shipping costs.

Also, when you send back your choice, please use a little JSON sketch like the one below so it's easy to read and plug in:

{
  ""solution"": {
    ""selected"": [<warehouse_to_open>, <warehouse_to_open>, ...],
    ""assignments"": [<chosen_open_warehouse>, <chosen_open_warehouse>, ...]
  }
}

Think of ""selected"" as the list of warehouse sites you decide to open, and ""assignments"" as the list (in the same order as the shops were given) of which opened warehouse each shop gets linked to. This is just the shape I want your answer in — a template, not the final numbers.

Please make sure to use the exact identifiers from the instance input when you fill this in — do not rename them or invent new ones. For example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"I run the city's bike repair program and need to pick which repair hubs to keep running, then send every reported fault to exactly one of the hubs that are open. Each hub has a startup price and can only handle a certain number of fixes, and getting a mechanic out to a fault costs something based on distance — so a better plan is the one that keeps the total bill as small as possible by adding up the opening fees for the hubs we choose and the travel cost for every repair. Nothing can be left unassigned or sent to two places, and no hub can be asked to do more than its limit. The concrete details — locations, opening costs, capacities and reported faults — are shown below.

Here are the details for the 8 candidate hubs and the 17 reported faults:
Hub F1 would cost 300.0 to open and can handle up to 384.0 fixes.
Hub F2 would cost 300.0 to open and can handle up to 256.0 fixes.
Hub F3 would cost 300.0 to open and can handle up to 376.0 fixes.
Hub F4 would cost 300.0 to open and can handle up to 425.0 fixes.
Hub F5 would cost 300.0 to open and can handle up to 430.0 fixes.
Hub F6 would cost 300.0 to open and can handle up to 378.0 fixes.
Hub F7 would cost 300.0 to open and can handle up to 435.0 fixes.
Hub F8 would cost 300.0 to open and can handle up to 503.0 fixes.

I'll pick which hubs to open and assign every fault so all 17 are covered within capacities and the total of opening fees plus travel costs is minimized.

Also, when you send back the plan, please stick to this simple JSON shape so I can read it easily:

{
  ""solution"": {
    ""selected"": [<hub_to_open>, <hub_to_open>, ...],
    ""assignments"": [<assigned_hub>, <assigned_hub>, ...]
  }
}

This is just a sketch of the shape I expect, not the real answer — fill the arrays with the actual hub identifiers from the instance. ""selected"" is the list of hubs you choose to keep running; ""assignments"" is a list that, for each reported fault in the same order as the input, gives the single open hub that will handle it.

Please don't invent new labels or change the identifiers from the instance — use them exactly as given.  
For example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"Out in the field, the food bank team must choose a handful of distribution points to staff and then direct every recipient area to exactly one of those staffed points. Each staffed point has a price tag to keep it open and each assignment from a point to an area has a delivery cost, so the best-looking plan is the one with the lowest total cost — add the staffing cost of each open point to all the delivery costs for the assignments. Each area must be covered once and only once, and each staffed point has a maximum amount it can serve, so assignments must stay within those limits. The concrete figures are provided below.

Just to keep things tidy, when you send the plan back please use this simple JSON layout so I can read it reliably:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<site_assigned_to>, <site_assigned_to>, ...]
  }
}

""selected"" is where you list the distribution points you'll staff (one placeholder per open point). ""assignments"" is a list showing, for each recipient area (in the same order as the instance), which staffed point it gets assigned to. Think of it like filling out a short form — who we open, and who goes where.

This JSON is just the expected shape — a sketch, not the actual filled-in answer.

Please use the exact identifiers from the instance input when you fill this in — do not rename them or invent new labels. 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"There’s a bit of a balancing act at the returns desk: choose a subset of repair hubs to keep running, then route each incoming device to one of those hubs. Each hub charges a fixed amount to stay active and can only process a limited number of devices, and moving a device to a hub adds a per-item cost. The smart plan is the one that keeps the total expense (hub-running fees plus device-movement costs) as small as possible, with every returned device assigned once and no hub given more than it can handle. The exact details — what each hub costs and how many devices they can take — are shown below.

Think of ""selected"" as the list of repair hubs you decide to keep running, and ""assignments"" as, for each returned device in the order they were listed, which hub it gets routed to. It's just a sketch of the form I need, not the actual final answer.

Please use the exact identifiers from the instance input — do not rename them or invent new labels. Valid identifiers look like plain numbers such as ""1"" or ""23"", single capital letters like ""A"" or ""B"", or a capital letter followed by digits like ""A1"" or ""X7"".","{'opening_costs': [400.0,

CFLP,CFLP,"Recently the team mapped out options for neighborhood meal centers: which ones to bring online and which households each should handle. Bringing a center online requires paying its activation cost, and every center can only cover a fixed amount of demand. Serving a household from a particular center also costs something (distance, time, etc.). Every household must be assigned to exactly one active center—no splitting across centers—and no active center can exceed its service limit. The best plan keeps the total cost (activation costs plus all delivery costs) as low as possible; that total is just the sum of the centers’ activation fees that are used plus all the household delivery costs. The specific numbers appear below.

There are 7 centers and 19 households in this instance.

Also, when you send back the actual plan, please use this JSON layout so everything lines up cleanly:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

""selected"" is the list of centers you decide to bring online (use the exact IDs from the instance). ""assignments"" is a list, one entry per household in the same order as the input, giving the open center that will serve that household. Think of it like a simple form — this block just shows the shape I need, not the final answers.

Please make sure to use the identifiers exactly as they appear in the instance input — do not rename them or invent new labels. For example:
- Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [400.0, 400.0,

CFLP,CFLP,"Recently the festival team was working out where to install temporary water stations and how to route attendees, with the rule that each attendee must go to one installed station and stations can’t handle more people than their limit. Each station has a fee to set up and people have different walking distances depending on where they’re sent. The idea is to pick stations and assignments so the combined cost — setup fees plus total walking distance — is as low as possible. The actual station choices, capacities, fees, and attendee numbers will be shown below.

There are 8 stations and 19 attendee groups in this instance.

If you want to submit a candidate solution, just stick to this little JSON shape so it's easy to parse — here’s the informal template I’ll expect:

{
  ""solution"": {
    ""selected"": [<station_to_open>, <station_to_open>, ...],
    ""assignments"": [<chosen_open_station>, <chosen_open_station>, ...]
  }
}

Pretty simple: ""selected"" is where you say which water stations you plan to set up, and ""assignments"" says, for each attendee in the input order, which opened station they should go to. This is just a sketch of the shape I need, not the actual answer.

Please make sure you use the exact identifiers from the instance input — do not rename them or invent new labels. Valid identifiers look like plain numbers such as ""1"" or ""23"", single capital letters like ""A"" or ""B"", or a capital letter followed by digits like ""A1"" or ""X7"".","{'opening_costs': [128.0,

CFLP,CFLP,"We’re juggling dorm space for the upcoming semester and have to choose which wings to bring online and where each student should live. The task is to open some wings (each has an opening price and a fixed number of beds) and then assign every student to a single opened wing without exceeding those beds. Better choices are the ones that minimize what we pay overall: add up all wing-opening expenses and the distance or hassle cost for every student move — that total is what we want as small as possible. Concrete details will be shown below.

There are 8 wings and 19 students in this instance.

One more small thing: when you send the solution back, please use this little JSON shape so I can read it automatically — just a list of the wings you open and a list that says, for each student in the input order, which opened wing they’ll live in.

{
  ""solution"": {
    ""selected"": [<wing_to_open>, <wing_to_open>, ...],
    ""assignments"": [<assigned_wing>, <assigned_wing>, ...]
  }
}

""selected"" is where you put the identifiers for the wings you decide to open. ""assignments"" lists, in the same order as the students showed up in the input, which opened wing each student gets assigned to. Super informal: think of ""selected"" as the checkboxes for which wings we flip on, and ""assignments"" like the roommate list showing everyone's wing.

This JSON is just a sketch of the shape I need — not the real answer itself. Please make sure to use the exact identifiers from the instance input (don’t rename them or invent new labels). Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [300.0, 300.0,

CFLP,CFLP,"Recently the team had to map out which neighborhood lockers to activate and how to route customers: activating a locker incurs a fixed charge, each locker has a parcel limit, and customers can’t have their parcels split across multiple lockers — each customer goes to one active locker only. To pick the best setup, add up all activation charges for the lockers opened and all customer travel costs to their assigned lockers; the setup with the smallest total cost is preferable. The detailed list of lockers, capacities, costs and customers appears below.

If you could, please return the final choice in this simple JSON shape so it's easy to parse — nothing fancy, just the two bits we need.

{
  ""solution"": {
    ""selected"": [<locker_to_open>, <locker_to_open>, ...],
    ""assignments"": [<chosen_open_locker>, <chosen_open_locker>, ...]
  }
}

""selected"" is the list of neighborhood lockers you activate (the ones you pay the fixed charge for). ""assignments"" is a customer-by-customer list (in the same order as the customers in the instance) saying which opened locker each customer will use. This is just the skeleton of the answer — fill in the actual identifiers from the instance when you submit the solution.

Please make sure to use the exact identifiers from the instance input — do not rename or invent labels. Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [600.0, 600.0,

CFLP,CFLP,"We’re coordinating post-disaster sheltering and have to decide which temporary shelters to stand up and which families go where, making sure no household gets split and no shelter has more people than it can handle. Each potential shelter has a price to get it running and a limit on how many people it can take, and every family must be assigned to one of the shelters we open. The goal is to keep the overall expense as low as possible — just tally the opening costs for the shelters we choose plus the transport cost for each family’s move, and aim for the lowest total. The specific numbers and options are listed below.

Also, when you send back your choice, please follow this simple JSON layout so it's easy to read and check:

{
  ""solution"": {
    ""selected"": [<shelter_to_open>, <shelter_to_open>, ...],
    ""assignments"": [<chosen_shelter>, <chosen_shelter>, ...]
  }
}

This just means: ""selected"" is the list of shelters we decide to open, and ""assignments"" is a list (in the same order as the families in the input) saying which opened shelter each family goes to. Think of it like filling out a quick form — which sites are active, and which site each family is sent to. The JSON above is only a sketch of the shape I need, not the actual solution.

Please make sure you use the exact identifiers from the instance input — do not rename them or invent new labels. To be clear: Valid identifiers look like plain numbers such as ""1"" or ""23"", single capital letters like ""A"" or ""B"", or a capital letter followed by digits like ""A1"" or ""X7"".","{'opening_costs': [258.0, 128.0, 296.0, 225.0, 310.0, 373.0, 329.0, 179.0, 321.0], 'capacities': [366.0, 314.0, 504.0, 504.0, 580.0, 415.0, 456.0, 549.0, 316.0], 'connection_costs': [[557.0,

CFLP,CFLP,"Many operators face the same trade-off: turn on enough edge servers to serve everyone but not so many that setup costs blow up, and assign each device to a single server so no traffic is split and every server stays within its capacity. To pick the best arrangement, total up the cost of provisioning the chosen servers and the latency cost for each device’s connection; the arrangement with the lowest total is preferred. The full set of numbers and choices is shown below.

There are 8 candidate edge servers and 18 user devices in the scenario.
Edge server F1 can be provisioned at cost 119.0 and offers capacity 309.0.

The preferred arrangement minimizes the combined provisioning and latency costs.

If you want to send the answer back, just use this little JSON shape — nothing fancy, just a compact form I can read easily.

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

Think of ""selected"" as the list of servers you're switching on, and ""assignments"" as, in order, which server each device talks to. Super simple: one server per device, and the arrays should line up with the instance ordering.

This is just a sketch of the shape I need — not the actual answer yet. Please make sure to use the exact identifiers from the instance input, with no renaming and no new labels. 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"There’s a weekend market coming and someone has to choose which vendor stalls to rent and which sellers go into which rented stalls. Each stall has a rental fee and a maximum amount of space, while each seller needs a fixed amount of space and will incur a setup/travel cost to use a particular stall. Sellers can’t be split between stalls and every seller must have exactly one assigned stall; also a stall can’t hold more seller space than it allows. The goal is straightforward: pick stalls and assignments that keep the total bill — stall rentals plus sellers’ setup/travel costs — as small as possible. The concrete details follow below.

There are 7 candidate stalls and 16 sellers.
Stall F1 has a rental fee of 600.0 and a space limit of 700.0.
Stall F2 has a rental fee of 600.0 and a space limit of 700.0.
Stall F3 has a rental fee of 600.0 and a space limit of 700.0.
Stall F4 has a rental fee of 600.0 and a space limit of 700.0.
Stall F5 has a rental fee of 600.0 and a space limit of 700.0.
Stall F6 has a rental fee of 600.0 and a space limit of 700.0.
Stall F7 has a rental fee of 600.0 and a space limit of 700.0.

Choose stalls and assignments that minimize the total of stall rentals plus sellers' setup/travel costs.

Also, when you send back your answer, just use this simple JSON shape so I can read it easily — nothing more, nothing less.

{
  ""solution"": {
    ""selected"": [<stall_to_rent>, <stall_to_rent>, ...],
    ""assignments"": [<chosen_rented_stall>, <chosen_rented_stall>, ...]
  }
}

""selected"" is where you list the stalls you'll rent. ""assignments"" lists, in the same order as the sellers show up in the instance, which rented stall each seller goes into. Super casual: think of ""selected"" as the list of booths on the lease, and ""assignments"" as the name-tag telling each seller which booth to set up at.

This JSON is just a sketch of the shape I expect, not the actual solution itself.

Please make sure to use the exact identifiers from the instance input — do not rename them or invent new ones. Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [600.0, 600.0,

CFLP,CFLP,"I run the campus dining operation and have to pick which satellite kitchens to keep cooking and which to close, then decide which whole student groups each open kitchen will feed. No group gets split up, and no kitchen is asked to handle more students than it can actually serve. A good plan is the one that keeps the overall bill low — that bill being the sum of the kitchens’ running costs plus whatever it costs to get food from a kitchen to a group — and the specific kitchen sizes, opening costs, and group demands are shown below.

Oh, and when you reply with a plan, please follow this little JSON layout so I can read it easily — nothing fancy, just a consistent shape. Here's the sketch I like:

{
  ""solution"": {
    ""selected"": [<kitchen_to_open>, <kitchen_to_open>, ...],
    ""assignments"": [<chosen_open_kitchen>, <chosen_open_kitchen>, ...]
  }
}

""selected"" is where you list which kitchens you decide to keep running (use the exact kitchen IDs from the instance). ""assignments"" is a list that, in order, says which open kitchen feeds each student group (again, use the exact IDs). This is just the expected shape — a sketch, not the final plan.

Please make sure you use the identifiers exactly as they appear in the instance input — no renaming and no new labels. Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [400.0, 400.0,

CFLP,CFLP,"We manage a cluster of possible driver stations and have to choose which ones to bring people in to staff, then send each rider to exactly one staffed station for pickup. Staffing a station costs money and each station can only cover so many riders, while every rider assigned to a station creates an extra pickup detour cost. A good plan keeps the overall expense as small as possible — sum up the staffing charges for the stations opened and the detour costs for all rider pickups — while making sure every rider is tied to a single staffed station and no station exceeds its driver limit. The specific numbers and scenarios follow below.

Oh, and one more practical thing — when you send back your plan, please put it in a little JSON package so it's easy to read by humans or tools. Something casual like this shape will do:

{
  ""solution"": {
    ""selected"": [""<station_to_staff>"", ""<station_to_staff>"", ...],
    ""assignments"": [""<staffed_station_for_rider>"", ""<staffed_station_for_rider>"", ...]
  }
}

Think of ""selected"" as the list of stations you're deciding to staff, and ""assignments"" as which staffed station each rider gets sent to (one entry per rider). This is just the shape we want — a sketch, not the final numbers.

Please remember: use the exact identifiers from the instance input when you fill those placeholders — don't rename them or invent new labels. 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"There’s a neighborhood project where a few bookmobile stops can be set up, but not all of them at once. The team needs to decide which stops to operate, send each reader to exactly one of the active stops (no splitting visits), and watch that no stop handles more visitors or checkouts than it can manage. Better choices are the ones that keep total spending down — add the cost to run the chosen stops and the travel time for every reader, and aim for the smallest total. The concrete details about stops, costs, and reader counts appear below.

Oh, and just so we're on the same page, please send the solution in this simple JSON layout (just a little form I like to use):

{
  ""solution"": {
    ""selected"": [<stop_to_open>, <stop_to_open>, ...],
    ""assignments"": [<assigned_open_stop>, <assigned_open_stop>, ...]
  }
}

This little sketch means: ""selected"" lists the stops you'll run, and ""assignments"" gives, for each reader in the same order as the input, which open stop they should go to. It's just the shape I need — not the final numbers or choices.

Please remember to use the exact identifiers from the instance input — do not rename them or invent new labels. Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [258.0, 128.0,

CFLP,CFLP,"Someone running a local cloud-kitchen brand needs to decide which ghost kitchens to pay to activate and which active kitchen will handle each incoming order. Orders can’t be split across kitchens — each goes to one kitchen — and no kitchen should be overloaded beyond its capacity. What makes one setup preferable is simple money math: the total bill is the sum of every kitchen’s activation fee that’s paid plus the fulfillment cost for every order, and the goal is to keep that total as small as possible. The detailed instance — kitchens, costs, capacities and orders — follows below.

Also, to keep things machine-friendly, please return the result in this simple JSON shape so I can pick out which kitchens you turned on and which kitchen handles each order:

{
  ""solution"": {
    ""selected"": [<kitchen_to_open>, <kitchen_to_open>, ...],
    ""assignments"": [<assigned_kitchen>, <assigned_kitchen>, ...]
  }
}

The idea is straightforward: ""selected"" is the list of ghost kitchens you decide to activate, and ""assignments"" is a list (in the same order as the orders in the instance) naming which active kitchen handles each order. Think of it like a short form: which kitchens are paid for, and who cooks each order.

This JSON is just a sketch of the expected shape — not the final plan. One important rule: use the exact identifiers from the instance input when you fill this in — do not rename them or invent new labels. Valid identifiers look like plain numbers such as ""1"" or ""23"", single capital letters like ""A"" or ""B"", or a capital letter followed by digits like ""A1"" or ""X7"".","{'opening_costs': [600.0,

CFLP,CFLP,"Someone has to map out which recycling points should be up and running and which households will use each one. Every household must be assigned to one open point only, and each point has a maximum intake it can’t exceed. The “better” solution is the one with the lowest total cost: tally the costs to open the selected points plus all residents’ hauling effort to their assigned spots, and choose the assignment with the smallest total. The exact data and choices are shown below.

There are 8 collection points and 19 households in this instance.

When you send your solution, please follow this simple JSON layout so I can read it easily:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

""selected"" is where you list the recycling points you want to open. ""assignments"" is a list that, for each household in the instance (in the same order as the input), says which open point that household will use. Think of it like filling out a short form: which sites are active, and then which active site each household goes to.

This JSON is just a sketch of the shape I expect, not the actual answer — replace the placeholders with the real identifiers from the instance.

Please make sure all identifiers are used exactly as they appear in the instance input — no renaming and no new labels. 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"We’ve got a list of possible charging locations around town and a fleet of electric vehicles that need to be sent to stations for service. The decision is which of those locations to open (each one costs money to commission) and which station each vehicle should visit; every vehicle must go to one open station only, and every station can only take so many vehicles. A good choice is the one that keeps the overall expense down — tally the commissioning fees for the opened stations plus all the extra driving each vehicle does, and make that total as small as possible. Full specifics about sites, their limits, and the cost numbers appear below.

You can just return the answer in this little JSON layout so it's easy to read and machine-friendly:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

""selected"" is the list of charging sites you decide to open (those cost money to commission). ""assignments"" is a list with one entry per vehicle saying which open site that vehicle will go to. Think of it like filling out a form — which stations are active, and where each vehicle is assigned. This is only a sketch of the shape I need, not the actual answer.

Please make sure to use the exact identifiers from the instance input — do not rename them or invent new labels. 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"Recently the campus IT group had to map out which shared printers to install and how to route staff print jobs to those printers. The goal was to minimize the overall cost, which is just the sum of the installation costs for the printers that are put in plus the transfer or delay cost for each document sent to its chosen printer. Every print job must be sent as a whole to a single installed printer, no printer can exceed its duty capacity, and no job can be left unassigned. The full list of printer options, costs, capacities and the print jobs is provided below.

There are 8 printers and 18 jobs in this instance.

If you could return the plan in a simple machine-friendly way, that would be great — something like this JSON layout so it's easy to check and parse.

{
  ""solution"": {
    ""selected"": [<printer_to_install>, <printer_to_install>, ...],
    ""assignments"": [<assigned_printer>, <assigned_printer>, ...]
  }
}

Think of ""selected"" as the list of printers you'll actually install, and ""assignments"" as, for each print job in the same order they were listed in the instance, which installed printer that job gets sent to. Super casual: selected = which printers we put in, assignments = where each job goes.

This JSON is just a sketch of the shape I want your answer to follow — not the final plan itself.

Please be careful to use the exact identifiers from the instance input when filling in those placeholders — do not rename or invent labels. For example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"There’s a simple trade-off in town: keep more drop-off centers so neighborhoods travel less, or keep fewer centers to save on upkeep — but whichever plan is chosen, each neighborhood’s trash must go to one place and no center can take more than its limit. Each open center has a maintenance cost, each neighborhood-to-center route adds hauling distance, and the aim is the plan that makes the combined upkeep plus hauling as small as possible while respecting site capacities and keeping every neighborhood’s trash intact and unsplit. The actual list of centers, capacities, costs, and neighborhood demands appears below.

When you send the plan back, do it in this little JSON shape so it's easy to check automatically and still human-readable:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<assigned_site>, <assigned_site>, ...]
  }
}

Here, ""selected"" is where you list the drop-off centers you decide to keep open, and ""assignments"" is, in order, which open center each neighborhood sends its trash to. Think of it like a simple form: selected = open centers, assignments = each neighborhood's chosen center. This JSON is just a sketch of the shape I need — not the final plan itself.

Please use the exact identifiers from the instance input when you fill this in — do not rename them or invent new labels. For example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"Recently the team had to map out where to put service stations and how to assign arriving guest groups so nobody ends up split between stations and no station gets swamped. Each potential station comes with a setup charge and a cap on how many people it can serve, while each guest group has a cost to be served from each station. The idea is to open some stations and send every group to exactly one of the opened stations, keeping assignments within capacity, and then total up the cost: station setup charges for those opened plus the service/travel costs for all group assignments — the lower that total, the better. The specific station choices, capacities, costs, and guest group list are below.

Oh, and when you send the actual picks and assignments back, please follow this little JSON layout so it's easy to parse and check — just a simple sketch of the shape I expect:

{
  ""solution"": {
    ""selected"": [<station_to_open>, <station_to_open>, ...],
    ""assignments"": [<station_for_group>, <station_for_group>, ...]
  }
}

Pretty straightforward: ""selected"" is the list of stations you decide to set up, and ""assignments"" is the list (in the same order as the guest groups were given) of which opened station each group goes to. Think of it like filling out a form: pick the stations you open, then for each guest group write the station you assigned them to.

This JSON is just a sketch of the expected shape, not the actual solution — fill in the real station identifiers from the instance when you reply.

Please make sure you use the exact identifiers from the instance input — do not rename them or invent new labels. Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [525.0, 365.0,

CFLP,CFLP,"Out in the district planners are choosing which pantry locations to operate and routing every family to a single open pantry, taking care not to overload any pantry’s storage. A good plan is judged by total cost — the sum of the running charges for the open sites plus the cost to serve all the families — so the plan with the lowest combined cost wins. The concrete inputs and figures come after this.

Oh, and when you send the plan back, please follow this simple JSON layout so I can read it easily:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_site>, <chosen_site>, ...]
  }
}

Think of ""selected"" as the list of pantry sites you'll keep running, and ""assignments"" as which open pantry each family goes to (one entry per family, in the same order as the family list). This is just a sketch of the shape I expect — not the final plan itself.

Please be sure to use the exact identifiers from the instance input when filling this out — don't rename sites or invent new labels. 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"One day the ops team had to trim costs: there are several data centers that can be kept on for a fee and each has finite server capacity, and every application must be assigned to a single active center. The task is to pick which centers to keep running and assign every app to exactly one of them, without exceeding any center’s capacity or duplicating assignments. The goal is to minimize the overall outlay — total cost equals the sum of running fees for the centers that are on plus the latency/connection cost for each app’s assignment — so choose the setup with the smallest total. The detailed instance information follows below.

Also, just so we're on the same page, please give the solution using this simple JSON shape when you answer — nothing fancy, just that structure so it's easy to parse:

{
  ""solution"": {
    ""selected"": [<center_to_keep_on>, <center_to_keep_on>, ...],
    ""assignments"": [<chosen_open_center>, <chosen_open_center>, ...]
  }
}

Think of ""selected"" as the list of data centers you decide to keep running (one placeholder per center), and ""assignments"" as, in order, which running center each application gets assigned to. Super informal: ""selected"" = which centers are on, ""assignments"" = where each app goes.

This JSON is only a sketch of the expected shape, not the actual answer.

Please make sure to use the exact identifiers from the instance input — do not rename them and do not invent new labels.
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"Someone in operations has to map orders to active micro-fulfillment centers and decide which centers to open. Opening a center carries a fixed fee and each center can only process a limited number of parcels; each order must go to exactly one open center and centers can’t take on more than their throughput allows. The quality of any decision is judged by the total expense: add the activation fees for the centers that are opened plus the routing cost for all orders — the plan with the lowest total is preferred. The exact center fees, capacities, and order list are shown below.

Also, when you send back the plan, please use this little JSON layout so I can read it automatically — just a casual shape for the answer:

{
  ""solution"": {
    ""selected"": [<center_to_open>, <center_to_open>, ...],
    ""assignments"": [<chosen_open_center>, <chosen_open_center>, ...]
  }
}

""selected"" is where you list the centers you decide to open (one identifier per opened center). ""assignments"" is a list that, for each order in the same order as the input, gives the identifier of the open center that will handle that order. Super informal: think of ""selected"" as the checkboxes you tick and ""assignments"" as the column where you write which box each order goes into.

This JSON is just a sketch of the expected shape — not the actual answer. Make sure every identifier you put in here matches the instance input exactly — no renaming and no new labels.

Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [400.0, 400.0,

CFLP,CFLP,"Across the county the goal is to set up a handful of mobile clinic locations and then send each patient to exactly one of the opened locations, making sure no location is overloaded. Each possible location has a cost to deploy and a capacity limit, and routing a patient to a location brings a travel or treatment cost. One rollout is better than another if its overall cost — the sum of the deployment costs for the chosen locations plus the travel/treatment costs for everyone scheduled there — is lower, with every patient assigned to a single open location and each location kept within its capacity. The concrete details are shown below.

Also, when you send the rollout back, please follow this little JSON layout so it's easy to check automatically. Here's the shape I expect:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

Think of ""selected"" as the list of clinic sites you decide to deploy, and ""assignments"" as who goes to which opened site (one entry per patient, in the same order the patients appear in the instance). This is just the format sketch — not the actual numbers or choices.

Please make sure all identifiers you use match the instance input exactly — no renaming and no invented labels. 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.

CFLP,CFLP,"Recently the planners talked about which docking stations to activate and how to group riders around them. Every station that’s turned on comes with a fixed cost, and each rider’s distance or inconvenience to their dock adds a small extra cost, so the plan that’s preferred is the one with the lowest combined cost — station start-up fees plus all riders’ access costs. It’s required that each rider be matched to a single open station and that no station be asked to handle more riders than its capacity. The detailed numbers are provided below.

There are 7 candidate docking stations and 15 riders to assign.
Docking station F1 would cost 432.0 to activate and can serve up to 466.0 riders.
Docking station F2 would cost 114.0 to activate and can serve up to 307.0 riders.
Docking station F3 would cost 121.0 to activate and can serve up to 311.0 riders.
Docking station F4 would cost 312.0 to activate and can serve up to 406.0 riders.
Docking station F5 would cost 103.0 to activate and can serve up to 302.0 riders.
Docking station F6 would cost 336.0 to activate and can serve up to 418.0 riders.
Docking station F7 would cost 472.0 to activate and can serve up to 486.0 riders.

The planners will prefer the assignment with the lowest combined station activation and riders' access costs.

Also, when you reply with the plan, please stick to this simple JSON layout so it's easy to parse:

{
  ""solution"": {
    ""selected"": [<station_to_open>, <station_to_open>, ...],
    ""assignments"": [<chosen_open_station>, <chosen_open_station>, ...]
  }
}

This just sketches the shape we expect—nothing more. In plain terms: ""selected"" is the list of docking stations you decide to turn on, and ""assignments"" gives, for each rider (in the same order as the input), the identifier of the open station they're assigned to. Keep it casual and concise.

Please make sure to use the exact identifiers from the instance input — do not rename them or invent new labels. Valid identifiers look like plain numbers such as “1” or “23”
- single capital letters like “A” or “B”
- or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [432.0, 114.0, 121.0, 312.0, 103.0, 336.0, 472.0], 'capacities': [466.0, 307.0, 311.0, 406.0, 302.0, 418.0, 486.0],

CFLP,CFLP,"Out in the district the challenge is picking which vending spots to fill and then assigning every customer zone to just one of the stocked spots. Filling a spot comes with a stocking fee, and each zone picks up an inconvenience cost depending on how far its assigned spot is; to judge any arrangement, total up all the stocking fees plus all the inconvenience costs — that combined total determines how good the choice is. It’s also essential that no stocked spot serves beyond its capacity and that every zone is linked to one and only one stocked spot. The instance details follow below.

There are 7 candidate vending spots and 17 customer zones described below.

These entries let one total stocking fees and inconvenience costs to judge arrangements while ensuring capacities are respected and each zone is assigned to exactly one stocked spot.

Also, when you send your pick, please follow this little JSON layout so it's easy to read and check:

{
  ""solution"": {
    ""selected"": [<vending_spot_to_open>, <vending_spot_to_open>, ...],
    ""assignments"": [<chosen_vending_spot>, <chosen_vending_spot>, ...]
  }
}

Think of ""selected"" as the list of vending spots you decide to stock, and ""assignments"" as a parallel list saying which stocked spot each customer zone uses (one entry per zone). This is just a sketch of the shape I need — not the final answer itself.

Please use the exact identifiers from the instance input when you fill this in; do not rename them or invent new labels.
- ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs': [300.0,

CFLP,CFLP,"Picture this: a map dotted with possible sorting hubs, each one you can turn on for a fee and each one only able to handle so many deliveries. Every address on the map needs to be sent to one running hub, and if a hub is farther away the trip costs more. The job is to decide which hubs to power up and which hub each address uses so the total spending — the sum of hub running costs and all the per-address routing costs — ends up minimal, and no hub is asked to do more than it can. The exact figures and setup are shown below.

Oh, and one more practical thing — please give the final plan in this little JSON shape so it's easy to read and check:

{
  ""solution"": {
    ""selected"": [<hub_to_open>, <hub_to_open>, ...],
    ""assignments"": [<assigned_hub>, <assigned_hub>, ...]
  }
}

Here ""selected"" is where you list the hubs you decide to power up (use the exact hub IDs from the instance), and ""assignments"" is a list, in customer order, saying which opened hub each address will use. Think of it like filling out a short form: which hubs are on, and for each address which hub handles it. This is just the expected shape — not the final choices.

CFLP,CFLP,"There’s a small town council trying to set up shared garden plots: each plot has an entry fee and can only hold so many people, and each gardener has a different effort cost for working different plots. The decision is which plots to unlock and which single unlocked plot every gardener should be assigned to, while respecting each plot’s capacity limits and making sure everyone is assigned exactly once. The winning layout is the one with the lowest total bill — just add the fees for all unlocked plots plus the effort costs for every gardener’s assignment to get the final total. The specific numbers for fees, capacities, and effort are given below.

Also, when you reply, please follow this little JSON layout so I can read your choices easily — nothing fancy, just a tiny form I can parse:

{
  ""solution"": {
    ""selected"": [<plot_to_open>, <plot_to_open>, ...],
    ""assignments"": [<chosen_plot>, <chosen_plot>, ...]
  }
}

Think of ""selected"" as the list of garden plots you decide to unlock (one entry per unlocked plot), and ""assignments"" as the single unlocked plot each gardener will be sent to (the i-th entry in that list matches the i-th gardener in the instance). This block is just a sketch of the shape I need, not the actual final answer.

Please be careful to use the exact identifiers from the instance input — do not rename them or invent new ones. For example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"Many people don’t see how much thought goes into placing service vans: pick which vans to put into service, then give each service visit to exactly one of those vans, making sure no van is asked to do more than it can. Each van has a cost to deploy and a cap on workload, and every client visit costs travel money. The goal is the plan with the lowest total expense — simply add up the deployment costs for the vans used and the travel costs for all visits — while covering every request once and not overloading any van. The specific instance information is listed below.

Use these details to pick which vans to deploy and assign each request without exceeding any van's capacity.

You can just hand the plan back to me in a small JSON snippet like this — I find it the easiest way to keep things straight.

{
  ""solution"": {
    ""selected"": [<van_to_deploy>, <van_to_deploy>, ...],
    ""assignments"": [<assigned_van>, <assigned_van>, ...]
  }
}

""selected"" is the list of vans you decide to put into service (one entry per van). ""assignments"" is the list of which van handles each client visit (one entry per client, in the same order as the client list). Think of it like a simple form: pick the vans you open, then for each visit say which opened van covers it.

This JSON is just a sketch of the shape I expect, not the final plan itself. Please use the exact identifiers from the instance input when you fill it in — do not rename them or invent new labels. Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [221.0, 595.0,

CFLP,CFLP,"At the planning meeting the task was explained plainly: decide which local switching offices to switch on and make sure every subscriber is assigned to one and only one of the switched-on offices, with no office taking more subscribers than its capacity allows. Turning on an office costs money, and linking each subscriber to a particular office has its own cost, so the total cost for any plan is just the sum of the activation charges for opened offices plus all subscriber connection costs — the plan should minimize that total. The specific numbers for this instance are provided below.

Oh, and just so you know how I’d like the answer returned, a handy little JSON sketch is what I’m expecting — nothing fancy, just the shape of the response so it’s easy to check and parse.

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<subscriber_chosen_site>, <subscriber_chosen_site>, ...]
  }
}

Pretty simple: ""selected"" lists the offices you decide to switch on (their IDs), and ""assignments"" lists, in order, which switched-on office each subscriber is assigned to (by that office’s ID). Think of it like filling out a form: one line for which offices are active, another line saying who connects to which active office.

This JSON is just a sketch of the expected shape — not the actual final plan.

Please use the exact identifiers from the instance input: no renaming and no new labels. Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [400.0, 400.0,

They will select which centers to open and how to assign beneficiaries so the total of opening fees plus service costs is minimized.

When you're ready to send back the decisions, just stick to this simple JSON shape so it's easy to read and check:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

""selected"" is the list of centers you'll activate. ""assignments"" is the chosen active center for each beneficiary (one entry per beneficiary, in the same order as the input). Think of it like filling out a short form: which sites are on, and for each person, which open site they're assigned to.

This is just a sketch of the expected shape, not the actual answer.

Please use the exact identifiers from the instance input — don't rename them and don't invent new labels. Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.","{'opening_costs': [400.0, 400.0,

CFLP,CFLP,"At the dorm office the decision is to keep some laundry rooms open and close others, then assign each dormitory to exactly one of the rooms that remain open. Each machine room has a finite capacity, so assignments must fit within those limits. The way to judge plans is straightforward: total cost — tally up the operating costs for the chosen laundry rooms plus the travel or usage cost for every dorm’s assignment, and prefer the arrangement with the lowest combined total. No dorm can be left out or sent to more than one place. The particular figures are shown below.

If you want to send back a plan, just stick to this simple JSON shape so I can read it easily.

{
  ""solution"": {
    ""selected"": [<room_to_open>, <room_to_open>, ...],
    ""assignments"": [<chosen_open_room>, <chosen_open_room>, ...]
  }
}

Think of ""selected"" as the list of laundry rooms you decide to keep running, and ""assignments"" as, for each dorm in the same order they were given, which open room that dorm will use. This is just a sketch of the expected shape — not the actual answer.

Please make sure to use the exact identifiers from the instance input (do not rename them or invent new ones).
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”"".","{'opening_costs':

CFLP,CFLP,"We’re playing the role of a planning team deciding which local library sites to activate and how to send each neighborhood to a single branch. Opening a site costs money and each one can only handle so many people; sending a neighborhood to a branch adds a travel cost. The score for any arrangement is simply the sum of the opening costs and all the travel costs, and the aim is to keep that sum as small as we can while making sure every neighborhood is served by exactly one open branch and no branch is overloaded. The specific numbers will be listed below.

Also, when you send back a plan, use this simple JSON layout so everything’s easy to read and check:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

""selected"" is just the list of library sites we choose to open. ""assignments"" lists, in the same order as the neighborhoods appear in the instance, which open site each neighborhood goes to. Think of it like a short form: which branches we flip on, and for each neighborhood which branch it uses.

This JSON is only a sketch of the shape I need — not the filled-in answer yet. Please make sure to use the exact identifiers from the instance input; do not rename or invent new labels. 
- For example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':

CFLP,CFLP,"Picture this: a grocery chain choosing which branches to run for the season and then lining up every household to a single running branch. Each branch that’s kept open comes with an opening expense, and serving each household from a branch adds a travel or delivery cost — so the sensible thing is to pick stores and assignments that make the total bill (opening fees plus all travel costs) as small as possible. At the same time, every household must be assigned to one branch only, and no branch can exceed its stocking capacity. The exact store choices and household details appear below.

Also, when you send back your pick and the household line-up, please follow this simple JSON layout so it's easy to read and check:

{
  ""solution"": {
    ""selected"": [<site_to_open>, <site_to_open>, ...],
    ""assignments"": [<chosen_open_site>, <chosen_open_site>, ...]
  }
}

Think of ""selected"" as the list of branches you decide to keep open, and ""assignments"" as the list that, in order, tells which open branch each household is assigned to (one entry per household). Super informal sketch — it's just the shape I need, not the real answer itself.

Please use the exact identifiers from the instance input — no renaming, no made-up labels. 
- for example: ""Valid identifiers look like plain numbers such as “1” or “23”, single capital letters like “A” or “B”, or a capital letter followed by digits like “A1” or “X7”.""","{'opening_costs':
