LOP,LOP,"Someone in the back office measured how each dish plays with every other: for any two different plates, there’s a number saying how much better it is to serve A before B. The head chef’s job is to create a single tasting order that uses every plate exactly once and then add up those pairwise numbers according to that order. The better the sum, the smoother the tasting — so the plan is to find the order with the biggest combined harmony. The detailed menu and the pairwise numbers follow below.

# total_dishes=10
# dish_ids=A, B, C, D, E, F, G, H, I, J

# Meaning: this is a directed pairwise_harmony matrix over items in dish_ids (10 total). Entry at row preceding_dish_id=i and column following_dish_id=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).

Also, when you send back the final tasting order, you can just use a simple JSON snippet like this so it's easy to read and parse:

{
  ""solution"": [<first_dish>, <second_dish>, ..., <last_dish>]
}

This just means ""solution"" is an ordered list of the plates from the one served first to the one served last — swap each placeholder with the actual plate identifier from the instance. It's just the expected shape, not the actual answer itself.

Please make sure to use the identifiers exactly as they appear in the instance input — no renaming and no 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"".","[[0.0,

LOP,LOP,"Imagine a DJ lining up a deck of tracks and being told each song must appear once in a single, uninterrupted set. For every two different songs there’s a little energy value tied to playing one before the other, and the playlist’s magic comes from summing all those values for every ordered pair in the lineup. The challenge is to choose the order that makes that total sum as large as possible, with all songs included and no duplicates. The specific track names and the pairwise energy numbers are provided below.

LOP,LOP,"Backstage at the museum the crew debated the running order, agreeing it should be one continuous route that lists each painting just once so the visitors don’t miss or see anything twice.

LOP,LOP,"I was asked to put together a lineup of candidate interviews for a hiring round — everyone has to go once and only once, no skipping or repeats. For every pair of people there’s a little piece of insight you get if one is interviewed before the other, and the plan is to order the whole list so that, when you look at each pair and take whichever “before” benefit applies, the total of those benefits is as big as it can be. The lineup itself is the decision: which candidate goes first, second, third, and so on. The actual candidate names and the pairwise insight numbers are shown below.

B) We have a stack of candidates to interview and the job is to make a single run-through where each person is seen exactly once — nobody appears twice and nobody is left out. Between any two candidates there’s a known advantage to interviewing one before the other, and the trick is to pick an order so that, if you add up those pairwise advantages according to who comes earlier in your list, the sum is as high as possible. In short, choose the interview order that gives the biggest total comparative insight. The specific list of candidates and their pairwise values are given below.

C) There’s a hiring day coming up and the goal is to arrange the interviews into one clean sequence with every candidate interviewed one time only. For each pair of candidates someone already estimated how much more you’d learn if candidate A goes before candidate B, so the way to judge any ordering is to go through every pair and add the appropriate value for whoever is earlier. A better order is simply one that leads to a larger total when you add up those pairwise gains. The concrete candidate names and those pairwise numbers are shown below.

D) Someone in HR handed over a pile of profiles and a small table saying, for each pair, how much more clarity you get if person X is seen before person Y. The job is to make a single schedule where each candidate shows up exactly once, and then score that schedule by summing the pairwise benefits for every pair according to who’s earlier. The aim is to pick the order that ends up with the highest total sum. The exact candidates and their pairwise insights are listed below.

E) Recently the hiring lead wanted a single interview run where everyone gets one turn — no repeats, no misses. They’d already rated every head-to-head ordering with a number that tells how much comparative learning you get if one candidate comes before another; to compare schedules you just add up the appropriate numbers for all pairs based on the order you chose. The better schedule is the one with the bigger total. The specific candidate list and pairwise numbers follow below.

F) Many teams face the same little puzzle: line up a set of applicants so each is interviewed exactly once, and use the known “if A is before B” benefits to judge the lineup. For every pair there’s a number saying how much more useful it is to see one before the other, and you score a full schedule by summing those numbers for all pairs according to their positions. The best lineup is simply the one that gives the largest total sum. The actual candidates and the pairwise benefit values are shown below.

G) Back at the office the hiring coordinator scribbled down a rule: every candidate gets one interview, listed in one order, and for every pair there’s a recorded benefit if one comes before the other. To pick the order you mentally go through each pair, pick the benefit that corresponds to whoever is earlier, and add all those numbers up — the order with the biggest total is the one to run with. The candidate names and the full table of pairwise numbers are provided below.

H) On a busy Monday the team needed a single-line interview schedule where nobody is repeated and nobody is left off the list. They also had a cheat-sheet that says, for each pair, how much comparative insight results from interviewing person A before person B; a schedule is evaluated by summing those pairwise values for all pairs according to who’s earlier, and the schedule that yields the highest total sum is the one they want. The detailed list of candidates and the pairwise insight values appears below.

Here are the 5 candidates I must schedule: 0, 1, 2, 3, 4.
Meaning: this is a directed insight_gain matrix over items in candidate_ids (5 total). Entry at row candidate_before_id=i and column candidate_after_id=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).
insight_gain:
| candidate_before_id\candidate_after_id | 0 | 1 | 2 | 3 | 4 |
|---|---|---|---|---|---|
| 0 | 915.0 | 27.0 | 1.0 | 119.0 | 276.0 |
| 1 | 94.0 | 3757.0 | 38.0 | 130.0 | 1092.0 |

| 4 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 |
I'll choose the interview order that maximizes the total sum of these pairwise insight values.

If you want the result in a simple, machine-friendly form I can return it like this:

{
  ""solution"": [<first_item>, <second_item>, ..., <last_item>]
}

The ""solution"" entry is just the interview lineup from first to last — put the candidate identifiers in that array in the order you want them to be interviewed. This JSON is only a sketch of the shape I'll use, not the actual answer itself.

LOP,LOP,"Picture a small shop with a single long shelf that must show every product in a line, each item occupying one spot and only one. Between every two different products there’s a known cross-sell value for putting one in front of the other, and the overall score for any lineup is just the sum of those values for all pairs in that order. The point is to pick the sequence that gives the highest total score from those pair values. Nothing can be left off the shelf or shown twice. The full item list and the pairwise scores are shown below.

There are 10 products that must appear exactly once, listed here: A, B, C, D, E, F, G, H, I, J.
Meaning: this is a directed cross_sell_value matrix over items in product_ids (10 total). Entry at row leading_product_id=i and column following_product_id=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).

Find the order of the 10 products that maximizes the summed cross-sell values.

Also, when you send back the final lineup, just tuck it into this little JSON sketch so it's easy to read and parse:

{
  ""solution"": [<first_item>, <second_item>, ..., <last_item>]
}

Here ""solution"" should be the ordered list of every product from left to right on the shelf — first entry is the leftmost product, last entry is the rightmost. Think of it like filling out a simple form: one list, all items once, in the order you want them displayed. This is just the shape I expect, not the actual answer.

LOP,LOP,"Recently the magazine experimented with ordering algorithms, but the human task is familiar: arrange all the articles into one sequence so every article shows up exactly once. There’s a number tied to every ordered pair that says how much engagement is gained when article A precedes article B, and a full ordering gets a score by adding up those numbers for all pairs that follow that order. The aim is to get the ordering with the biggest total, and the exact article list and pair scores are laid out below.

I'll tally these contributions to pick the sequence with the highest total emotional lift.

Oh, and when you hand me the final ordering, please follow this simple JSON layout so it's easy to read and parse:

{
  ""solution"": [<first_item>, <second_item>, ..., <last_item>]
}

Here ""solution"" is just the single ordered list of speakers (from the one who goes first to the one who goes last). The angle-bracket names show the slots where each actual speaker identifier goes — think of it like the blanks on a form. This is just a sketch of the expected shape, not the actual final answer.

Please make sure you 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"".","[[678.0, 0.0, 18.0, 19.0, 9.0, 0.0, 10.0, 20.0, 144.0, 401.0], [54.0, 16.0, 3.0, 1.0, 30.0, 0.0, 0.0, 5.0, 11.0, 56.0], [418.0, 84.0, 45165.0, 37.0, 163.0, 6.0, 10.0, 22.0, 1010.0, 1146.0], [18.0, 4.0, 295.0, 302.0, 31.0, 0.0, 0.0, 0.0, 10.0, 63.0], [214.0, 67.0, 285.0, 18.0, 5348.0, 7.0, 3.0, 11.0, 201.0, 868.0], [80.0, 0.0, 30.0, 5.0, 35.0, 764.0, 2.0, 3.0, 17.0, 137.0], [290.0, 0.0, 2.0, 16.0, 29.0, 4.0, 9315.0, 25.0, 169.0, 921.0], [954.0, 463.0, 3306.0, 3.0, 6977.0, 28.0, 13.0, 275.0, 405.0, 1909.0], [337.0, 4.0, 341.0, 3.0, 32.0, 26.0, 0.0, 189.0, 12.0, 26.0], [1550.0, 0.0, 123.0, 10.0, 73.0, 28.0, 69.0, 203.0, 40.0, 729.0]]","[6, 7, 5, 3, 4, 2, 1, 9, 8, 0]",22567.0,"{'problem_type': 'LOP', 'num_nodes': 10, 'nodes': [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 'pairs': [{'from_id': 0, 'to_id': 1, 'weight': 0.0}, {'from_id': 0, 'to_id': 2, 'weight': 18.0}, {'from_id': 0, 'to_id': 3, 'weight': 19.0}, {'from_id': 0, 'to_id': 4, 'weight': 9.0}, {'from_id': 0, 'to_id': 5, 'weight': 0.0}, {'from_id': 0, 'to_id': 6, 'weight': 10.0}, {'from_id': 0, 'to_id': 7, 'weight': 20.0}, {'from_id': 0, 'to_id': 8, 'weight': 144.0}, {'from_id': 0, 'to_id': 9, 'weight': 401.0}, {'from_id': 1, 'to_id': 0, 'weight': 54.0}, {'from_id': 1, 'to_id': 2, 'weight': 3.0}, {'from_id': 1, 'to_id': 3, 'weight': 1.0}, {'from_id': 1, 'to_id': 4, 'weight': 30.0}, {'from_id': 1, 'to_id': 5, 'weight': 0.0}, {'from_id': 1, 'to_id': 6, 'weight': 0.0}, {'from_id': 1, 'to_id': 7, 'weight': 5.0}, {'from_id': 1, 'to_id': 8, 'weight': 11.0}, {'from_id': 1, 'to_id': 9, 'weight': 56.0}, {'from_id': 2, 'to_id': 0, 'weight': 418.0}, {'from_id': 2, 'to_id': 1, 'weight': 84.0}, {'from_id': 2, 'to_id': 3, 'weight': 37.0}, {'from_id': 2, 'to_id': 4, 'weight': 163.0}, {'from_id': 2, 'to_id': 5, 'weight': 6.0}, {'from_id': 2, 'to_id': 6, 'weight': 10.0}, {'from_id': 2, 'to_id': 7, 'weight': 22.0}, {'from_id': 2, 'to_id': 8, 'weight': 1010.0}, {'from_id': 2, 'to_id': 9, 'weight': 1146.0}, {'from_id': 3, 'to_id': 0, 'weight': 18.0}, {'from_id': 3, 'to_id': 1, 'weight': 4.0}, {'from_id': 3, 'to_id': 2, 'weight': 295.0}, {'from_id': 3, 'to_id': 4, 'weight': 31.0}, {'from_id': 3, 'to_id': 5, 'weight': 0.0}, {'from_id': 3, 'to_id': 6, 'weight': 0.0}, {'from_id': 3, 'to_id': 7, 'weight': 0.0}, {'from_id': 3, 'to_id': 8, 'weight': 10.0}, {'from_id': 3, 'to_id': 9, 'weight': 63.0}, {'from_id': 4, 'to_id': 0, 'weight': 214.0}, {'from_id': 4, 'to_id': 1, 'weight': 67.0}, {'from_id': 4, 'to_id': 2, 'weight': 285.0}, {'from_id': 4, 'to_id': 3, 'weight': 18.0}, {'from_id': 4, 'to_id': 5, 'weight': 7.0}, {'from_id': 4, 'to_id': 6, 'weight': 3.0}, {'from_id': 4, 'to_id': 7, 'weight': 11.0}, {'from_id': 4, 'to_id': 8, 'weight': 201.0}, {'from_id': 4, 'to_id': 9, 'weight': 868.0}, {'from_id': 5, 'to_id': 0, 'weight': 80.0}, {'from_id': 5, 'to_id': 1, 'weight': 0.0}, {'from_id': 5, 'to_id': 2, 'weight': 30.0}, {'from_id': 5, 'to_id': 3, 'weight': 5.0}, {'from_id': 5, 'to_id': 4, 'weight': 35.0}, {'from_id': 5, 'to_id': 6, 'weight': 2.0}, {'from_id': 5, 'to_id': 7, 'weight': 3.0}, {'from_id': 5, 'to_id': 8, 'weight': 17.0}, {'from_id': 5, 'to_id': 9, 'weight': 137.0}, {'from_id': 6, 'to_id': 0, 'weight': 290.0}, {'from_id': 6, 'to_id': 1, 'weight': 0.0}, {'from_id': 6, 'to_id': 2, 'weight': 2.0}, {'from_id': 6, 'to_id': 3, 'weight': 16.0}, {'from_id': 6, 'to_id': 4, 'weight': 29.0}, {'from_id': 6, 'to_id': 5, 'weight': 4.0}, {'from_id': 6, 'to_id': 7, 'weight': 25.0}, {'from_id': 6, 'to_id': 8, 'weight': 169.0}, {'from_id': 6, 'to_id': 9, 'weight': 921.0}, {'from_id': 7, 'to_id': 0, 'weight': 954.0}, {'from_id': 7, 'to_id': 1, 'weight': 463.0}, {'from_id': 7, 'to_id': 2, 'weight': 3306.0}, {'from_id': 7, 'to_id': 3, 'weight': 3.0}, {'from_id': 7, 'to_id': 4, 'weight': 6977.0}, {'from_id': 7, 'to_id': 5, 'weight': 28.0}, {'from_id': 7, 'to_id': 6, 'weight': 13.0}, {'from_id': 7, 'to_id': 8, 'weight': 405.0}, {'from_id': 7, 'to_id': 9, 'weight': 1909.0}, {'from_id': 8, 'to_id': 0, 'weight': 337.0}, {'from_id': 8, 'to_id': 1, 'weight': 4.0}, {'from_id': 8, 'to_id': 2, 'weight': 341.0}, {'from_id': 8, 'to_id': 3, 'weight': 3.0}, {'from_id': 8, 'to_id': 4, 'weight': 32.0}, {'from_id': 8, 'to_id': 5, 'weight': 26.0}, {'from_id': 8, 'to_id': 6, 'weight': 0.0}, {'from_id': 8, 'to_id': 7, 'weight': 189.0}, {'from_id': 8, 'to_id': 9, 'weight': 26.0}, {'from_id': 9, 'to_id': 0, 'weight': 1550.0}, {'from_id': 9, 'to_id': 1, 'weight': 0.0}, {'from_id': 9, 'to_id': 2, 'weight': 123.0}, {'from_id': 9, 'to_id': 3, 'weight': 10.0}, {'from_id': 9, 'to_id': 4, 'weight': 73.0}, {'from_id': 9, 'to_id': 5, 'weight': 28.0}, {'from_id': 9, 'to_id': 6, 'weight': 69.0}, {'from_id': 9, 'to_id': 7, 'weight': 203.0}, {'from_id': 9, 'to_id': 8, 'weight': 40.0}]}","[6, 7, 5, 3, 4, 2, 1, 9, 8, 0]",9,nl,0
LOP,LOP,"Back when the team experimented with segment order, they noticed a pattern: for any two distinct pieces, placing A before B gives a measurable retention gain (those gains are recorded). The constraint is straightforward — every piece must appear exactly once in the final lineup, no repeats, no omissions — and the episode’s success is measured by adding up the gains for all ordered pairs that occur in the chosen sequence. The aim is to pick the sequence with the highest total. The specific segment names and pairwise gains follow below.

LOP,LOP,"Picture this: the festival has one continuous short-film set and every possible head-to-head of films has a little preference score for which should come first. The job is to arrange every short exactly once into a single sequence, and then total all the scores for each pair where the first film is placed before the second — that total tells how well the sequence works for the audience. The full list of films and those pairwise scores is shown below.

# num_films=10
# film_ids=A, B, C, D, E, F, G, H, I, J

# Meaning: this is a directed pairwise_audience_score matrix over items in film_ids (10 total). Entry at row preceding_film_id=i and column succeeding_film_id=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).

When you're ready to give the film order back, just pop it into this little JSON layout so it's easy to read and parse:

{
  ""solution"": [<first_item>, <second_item>, ..., <last_item>]
}

Here ""solution"" is the single list that shows the screening order from the very first short to the very last one. The angle-bracket placeholders are just showing where each film's identifier goes — replace each placeholder with the exact film ID from the instance. This is only a sketch of the shape I want, not the actual answer itself.

Please use the identifiers exactly as they appear in the instance input — don't rename them or invent new labels.

LOP,LOP,"I’m putting together a single announcement that lists every new feature, and the trick is choosing the order. The plan is to list each feature once, no repeats, so that when a feature appears before another it can give a certain adoption lift — those lifts are different for each pair. The aim is to pick the sequence that makes the total adoption lift as big as it can be, by adding up the lift values for every pair where the earlier feature boosts the later one. The concrete numbers and details will be shown below.

""solution"" is just the list of features in the exact order you want them announced. The angle-bracket names are placeholders showing where each real feature identifier should go — think of it like filling in a form rather than writing a paragraph.

LOP,LOP,"Recently the test kitchen handed over a stack of recipes and the editor’s job became arranging them into one smooth chapter. Each time Recipe A precedes Recipe B there’s a known bit of extra menu-compatibility, and the chapter’s quality is just the sum of all those bits across every ordered pair — the goal is to make that sum as large as possible. Nothing can be left out or slotted in twice, and the concrete details follow below.

When you hand back the chapter order, a simple JSON reply is perfect — just a single list that runs from the first recipe to the last. Here’s the shape I’m expecting:

{
  ""solution"": [<first_item>, <second_item>, ..., <last_item>]

Think of ""solution"" as the ordered list of recipes in the chapter, from the one that should appear first through to the one that should appear last. This JSON is just a sketch of the shape I want you to follow, not the actual answer itself.

LOP,LOP,"Recently the team had to stitch together one continuous presentation from a pile of product pitches, and the rule was simple: every product gets exactly one spot, nothing left out, nothing repeated. Each time a product precedes another there’s a known persuasion boost for that ordering, and the whole show is judged by adding up all those boosts — the goal is to make that total as big as it can be. The detailed product names and their pairwise boosts are listed below.

There are 9 product pitches (A, B, C, D, E, F, G, H, I), each to be placed exactly once in the final presentation.
Meaning: this is a directed persuasion_boost matrix over items in product_ids (9 total). Entry at row preceding_product=i and column succeeding_product=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).
persuasion_boost:
| preceding_product\succeeding_product | A | B | C | D | E | F | G | H | I |
|---|---|---|---|---|---|---|---|---|---|
| A | 11831.0 | 388.0 | 9.0 | 10215.0 | 553.0 | 0.0 | 2.0 | 0.0 | 249.0 |

| I | 555.0 | 90.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 23.0 | 0.0 |
The team's goal is to order these 9 pitches to maximize the total persuasion boost.

If you want to hand your final order back in a tidy way, just drop it into this little JSON shape so it's easy to read and parse:

{
  ""solution"": [<first_item>, <second_item>, ..., <last_item>]
}

Think of ""solution"" as the single, ordered playlist — from the very first pitch to the one that closes the show.

LOP,LOP,"A friend who edits anthologies described the job like arranging people at a dinner: everyone gets one seat, no one sits twice, and the conversation carries better depending on who sits next to whom and who’s before whom in the course of the meal. Each time one chapter comes before another there’s a little compatibility score, and the overall harmony of the table of contents is just the total of all those scores across the whole seating plan — the higher that total, the better the flow from start to finish. The exact chapter list and all the compatibility numbers are listed below.

There are 5 contributed chapters to seat in the table of contents: 0, 1, 2, 3, 4.
Meaning: this is a directed compatibility_score matrix over items in chapter_ids (5 total). Entry at row earlier_chapter_id=i and column later_chapter_id=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).

LOP,LOP,"Recently a commuter playlist experiment started: one continuous ride, every track played once, no detours. For any two different songs there’s a known mood effect tied to their order, and the goal is to line them up so those effects combine into the largest overall mood boost. The way to score a lineup is simple — add together the mood gains for each time a particular song comes before another. The concrete pairwise values are shown below.

There are 5 tracks in the commute playlist: A, B, C, D, E.
Meaning: this is a directed mood_gain matrix over items in track_ids (5 total). Entry at row preceding_track_id=i and column following_track_id=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).
mood_gain:
| preceding_track_id\following_track_id | A | B | C | D | E |
|---|---|---|---|---|---|
| A | 2985.0 | 23.0 | 0.0 | 8.0 | 19.0 |

| E | 15.0 | 4.0 | 2.0 | 35.0 | 6479.0 |
Orderings of these 5 tracks are scored by summing the listed pairwise mood gains; the best playlist maximizes that total.

If you want to hand me a final playlist, use this simple JSON layout so it's easy to read and parse:

{
  ""solution"": [<first_track>, <second_track>, ..., <last_track>]
}

""solution"" is just the ordered playlist: the first entry is the very first song on the ride, the next entry is the second song, and so on until the last entry. The angle-bracket names are placeholders showing the shape I expect — replace them with the actual song identifiers from your instance when you give the final lineup.

LOP,LOP,"There’s a conference schedule to sort out, and ordering actually matters: someone has measured how much better it is if each speaker precedes another. So to see how good a particular order is, just add up those little numbers for every pair where the first speaker appears earlier in the lineup than the second. The task is to pick one single sequence that includes every invited speaker one time only, and that gives the largest total sum of those pairwise perks. The specific speakers and their pairwise values are listed below.

Below are the 7 invited speakers: 0, 1, 2, 3, 4, 5, 6.
Meaning: this is a directed benefit_if_precedes matrix over items in speaker_ids (7 total). Entry at row preceding_speaker_id=i and column following_speaker_id=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).

This little block is just a template: ""solution"" should be the full lineup from first speaker to last, and each entry in the list should be the exact identifier used in the instance for that speaker.

LOP,LOP,"In a small gallery project the job is to arrange the paintings in a single straight line to get the most engaging visitor journey. For each pair of paintings there’s a small impact number showing how much better it is when one is placed before the other, and the total effect of any ordering is simply all those numbers added up for every ordered pair. The requirement is to use every painting exactly one time — nothing left out and nothing repeated — and to adopt the ordering that yields the largest combined impact. The specific list of works and their pairwise impact values are shown below.

I'll use these to choose the module sequence that maximizes the total learning boost.

Also, when you give the final ordering, please use this simple JSON layout so I can pick it up automatically.

{
  ""solution"": [<first_item>, <second_item>, ..., <last_item>]
}

The ""solution"" array should list the lesson modules in the exact sequence you want them taught, from the first module to the last. Think of it like a form: one slot per position in the course, each filled with the module identifier. This JSON is just a sketch of the shape I expect — don't treat it as the actual answer unless you replace the placeholders with the real module IDs.

Please make sure to use the identifiers exactly as they appear in the instance input — no renaming and no new labels.

LOP,LOP,"I’m the email marketing manager putting together a campaign that’ll send a bunch of ad creatives in a row. The choice to make is the exact order to send them in. For any two creatives there’s a known effect if the first one appears before the second, and the campaign’s overall effectiveness is just the total you get by adding up each of those pairwise effects for every pair in the final line-up. Every creative has to be used once and only once — no repeats, no skipping anything. The concrete pairwise numbers and the list of creatives are shown below.

LOP,LOP,"Picture this: a stack of reception cards, each naming one event, and between every two cards there’s a note saying how much better it is to have card A before card B. The challenge is to lay out all the cards in one neat row — every event must be used exactly once — and then tally up all those little notes for that particular order. The order with the biggest total tally gives the best guest experience. The exact events and the pairwise notes are shown below.

Below are the 6 event cards: 0, 1, 2, 3, 4, 5.

*Meaning: this is a directed guest_experience_points matrix over items in event_list (6 total). Entry at row from_event=i and column to_event=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).*

LOP,LOP,"Someone in marketing lined up a handful of demos and now it’s time to decide the running order — and that order actually changes how persuasive the day will be. Between any two demos there’s a specific benefit to showing one ahead of the other, so for any full sequence you can compute a total persuasiveness by adding up all the pairwise benefits that occur in that order. The plan must use every demo once, no repeats, no skips, and the best sequence is the one with the biggest total sum. The specific demos and their pairwise values are shown below.

Here are the 5 demos: 0, 1, 2, 3, 4.

*Meaning: this is a directed pairwise_persuasion matrix over items in demo_ids (5 total). Entry at row demo_before_id=i and column demo_after_id=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).*

The optimal running order uses every demo once and maximizes the total summed pairwise persuasion.

If you want to hand the running order back to me in a tidy way, just use this little JSON shape — it makes it clear which demo goes first, second, and so on.

{
  ""solution"": [<first_item>, <second_item>, ..., <last_item>]
}

This shows the expected shape: ""solution"" is an ordered list with the demos in the exact running order (first item listed is shown first, last item listed is shown last). The angle-bracket placeholders just sketch where each demo identifier should go — replace them with the actual identifiers from the instance when you answer.

This JSON is just the shape I expect, not the final answer itself. Please use the identifiers exactly as they appear in the instance input — no renaming, no new labels.

When you send the final ordering back, just drop it into a tiny JSON object so it’s easy to parse — something casual, like this:

  ""solution"": [<first_item>, <second_item>, ..., <last_item>]

Pretty simple: ""solution"" holds an ordered list of the spreads from front to back — the first entry is the opener and the last entry is the closer. Think of the JSON as a little form: replace the placeholders with the actual spread identifiers from the instance input.

And when you reply, just pop the ordering into a tiny JSON snippet like this — keeps things simple and easy to parse:

{
  ""solution"": [<first_item>, <second_item>, ..., <last_item>]
}

The ""solution"" array is just the commits in the order you want them to appear, from first to last. Each placeholder like <first_item> stands in for the actual commit identifier from the input — think of it as a little form where you list every commit exactly once.

LOP,LOP,"I’m the late‑night DJ trying to stitch together a tight set from a pile of tracks. The trick is to put every song into one continuous run — no repeats, nothing left in the crate — and order them so the flow between each pair feels great. Each possible transition has a little engagement score, and the whole show’s success comes from adding up those scores for every consecutive pair; the higher that total, the better the ride. The exact tracks and their transition scores are shown below.

LOP,LOP,"Many people on the team are treating this like a puzzle: arrange the whole batch of images into a single chain so every picture appears once and no image is left out or repeated. There’s a tiny benefit assigned to every possible ordered pairing — if photo X comes before photo Y you pick up the listed amount — and the story’s overall strength is the sum of all those picked-up amounts across the entire ordering. So the goal is to order the pictures to collect the biggest total reward. The exact images and their pairwise rewards are shown below.

Here are the 7 photos (A, B, C, D, E, F, G) that must each appear once in the final chain.
Meaning: this is a directed pairwise_story_gain matrix over items in image_ids (7 total). Entry at row preceding_image_id=i and column following_image_id=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).

List each ordered pair so the total narrative gain for the full ordering can be computed.

LOP,LOP,"We’ve got a stretch of gallery and a stack of exhibits that all need to be placed in a single row — each item gets exactly one spot, nobody gets left out and nothing is doubled up. Between every two different exhibits there’s a given benefit for placing one ahead of the other, and the crowd’s overall reaction to a particular arrangement is just the sum of those little benefits for every time one piece comes before another. So the plan that gives the highest combined interest is the one to aim for. The exact exhibits and the interest values follow below.

Here are the 7 exhibits we need to place: 0, 1, 2, 3, 4, 5, 6.

*Meaning: this is a directed interest_gain matrix over items in exhibit_ids (7 total). Entry at row preceding_exhibit=i and column succeeding_exhibit=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).*

LOP,LOP,"There’s a small team planning a how-to guide, and they’re deciding the sequence of actions. For each pair of actions, there’s a number that measures how much better learners do if that specific action is taught before the other; the aim is to pick an order that makes the sum of all those pairwise numbers as large as possible. The plan must use every action one time only — nothing left out or repeated — and the concrete steps and their benefit numbers are shown below.

They must arrange the 8 steps 0, 1, 2, 3, 4, 5, 6, 7 into the single uninterrupted tutorial workflow; the following pairwise learning benefits apply:

They should choose an ordering of all 8 steps in 0, 1, 2, 3, 4, 5, 6, 7 that maximizes the total summed learning benefit.

Also, when you send the final sequence back, it helps to use a tiny JSON shape so it's clear and machine-friendly. Something like this will do:

{
  ""solution"": [<first_item>, <second_item>, ..., <last_item>]
}

Here ""solution"" is just the ordered list of actions from first to last — put each action's identifier in the array in the order you want them taught. This is only a sketch of the shape I expect, not the actual ordering.

Please use the exact identifiers from the instance input — don't rename them or invent new labels.

LOP,LOP,"I’m putting together a tasting flight and need to line up every bottle into one continuous progression. The trick is that for every pair of different wines there’s a little note saying how much better the palate gets if one is tasted before the other. The job is to pick an order that uses every wine exactly once—no skips, no duplicates—and that makes the whole flight as enjoyable as possible. That enjoyment is measured by adding up those pairwise improvement numbers for every time a wine appears before another, and the plan is to choose the order with the biggest total.

Think of it like filling in the blanks on a form — the array is just the lineup of wines, one identifier per slot. This JSON is only a sketch of the expected shape, not the actual answer.

All identifiers must be used exactly as they appear in the instance input — no renaming and no new labels.

LOP,LOP,"On a typical afternoon the assignment is simple: create one complete sequence of study topics with every topic included exactly once. There’s a reinforcement number for each directed pairing — how much benefit results if that particular topic comes before another — and the overall benefit of a sequence is the sum of those numbers for every pair that appears in that order. The task is to find the ordering with the biggest total sum, and the concrete details are provided below.

Concretely, there are 7 topics to place, listed as 1, 2, 3, 4, 5, 6, 7.

LOP,LOP,"Many people treat the morning like a tiny relay: each prep task passes the baton to the next, and every pass has a smoothness score. The job here is to set a single route that uses each task once, never repeats, and never leaves anything out. The quality of a route is simply the total you get by adding each pair’s smoothness when one task follows another, so the better route is the one with the largest total. The detailed tasks and their transition scores are provided below.

If you want to hand the route back in a tidy, machine-friendly way, just use this little JSON shape when you reply:

{
  ""solution"": [<first_item>, <second_item>, ..., <last_item>]
}

That's just the shape I expect: ""solution"" is an ordered list from the very first task to the very last one. Think of it like a short form where you drop in the tasks in the order you picked them — one appearance each, nothing duplicated. The JSON above is just a sketch of the format, not the actual answer.

Between every two speakers someone has worked out how much more engaging it is if A speaks before B — those are the little gains on the sheet. For any complete ordering, add up all the gains that apply (every time one presenter appears ahead of another you include that number) and the total is the event’s audience score. The goal is to arrange the speakers so that total score is as high as possible. The concrete numbers and names are listed below.

LOP,LOP,"There’s a cartoonist juggling a pile of panels, figuring out which to read first, second, third, and so on so the payoff is funniest and clearest. The rule is simple: use every panel once and only once — don’t drop any, don’t repeat any — and for every two panels there’s a little preference value that says how much better it is to put one before the other (it’s directional, so order matters). For any candidate ordering, the overall effect is just the sum of all those pairwise values where the earlier panel earns its listed bonus; the best order is the one with the largest total. The exact panels and their pairwise timing perks follow below.

The 10 panels are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, with the directional pairwise benefits listed below.
Meaning: this is a directed pairwise_benefit matrix over items in panels (10 total). Entry at row panel_before_id=i and column panel_after_id=j is the reward gained if i is placed BEFORE j in the final ordering (diagonal can be ignored).

When you send back the final ordering, please use this simple JSON shape so it's easy to read and check:

For each pair of ingredients someone has already written a bonus number that tells how good it is to have one placed before the other; the overall success is the sum of those bonuses for every pair depending on which one comes earlier.

""solution"" should be a single list that goes from the ingredient you want first to the one you want last.
