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). 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. This repo is only storage for data and published run outputs.

What is here

Area	Role
Instances	<challenge>/test/ — *.txt problem files under academic/ (literature sets) and tig/ (TIG tracks).
Published best-known values (academic)	CSV files next to those instances, e.g. knapsack/test/academic/standard-QKP/standard_qkp_bks.csv, job_scheduling/test/academic/bks.csv, vehicle_routing/test/academic/bks.csv, and the other knapsack academic BKS CSVs alongside their splits.
Long-run summary	<challenge>/results/summary_long_run_v*.csv — rolled-up metrics from the reference run (where that challenge has been published).
Convergence plots	<challenge>/results/plots/*.png — figures from that run (e.g. average gap vs. time), when present.
Solutions	<challenge>/results/solutions/ — final .solution files and optional time-stamped snapshots (.solution.<seconds>), laid out to mirror the corresponding instance paths under test/, plus runs.csv where exported.

Challenges: knapsack, job_scheduling, vehicle_routing. What appears under each challenge’s results/ folder depends on what has been published for that challenge (summaries, plots, solutions).
