# TIG Challenges Data

This repository holds **benchmark instances**, **reference objective data** for academic splits, and **artifacts from long reference runs** (aggregated summaries, convergence plots, and solution files) for the combinatorial challenges used in [The Innovation Game (TIG)](https://tig.foundation). It is meant as a stable place to download benchmarks and compare against those reference outputs.

Solver code, formats, and how to run or evaluate algorithms live in **[tig-foundation/tig-challenges](https://github.com/tig-foundation/tig-challenges)**. This repo is only storage for data and published run outputs.

## What is here

Layout matches this checkout (and may differ from older Hub revisions that used a `test/` prefix):

| Area | Role |
|------|------|
| **Instances** | `<challenge>/instances/` — `*.txt` instances under splits such as `TIG/`, `standard-QKP/`, `TeamFormation-QKP/`, `Dispersion-QKP/` (knapsack), `tig/`, `fjsp/`, `jsp/` (job scheduling), `TIG/` (vehicle routing), etc. |
| **Best-known values** | `knapsack/instances/bks.csv`, `job_scheduling/instances/bks.csv`, `vehicle_routing/instances/bks.csv`, plus any BKS CSVs alongside specific academic splits under `instances/`. |
| **Plots** | `<challenge>/plots/*.png` — convergence or summary figures when present. |
| **Solutions** | `<challenge>/solutions/` — published `.solution` files (and optional snapshots) mirroring instance paths where bundled, plus any exported `runs.csv`. |

Challenges: **knapsack**, **job_scheduling**, **vehicle_routing**. Not every challenge includes all of plots, solutions, and every split in a given clone.
