# ORBench problems and recorded results

100 synthetic inventory, assignment, and scheduling instances for the ORBench demo.

Organization dataset and collection are public. Live Gradio and the organization card are created by `scripts/publish.py`. Runnable Space source is stored in `demo/`. Collection: [Aria AI — OR + LLM Evaluation](https://huggingface.co/collections/AriaAICompany/aria-ai-or-llm-evaluation-6ab00e62b6dc6303fe9272e1).

Generated data, seed 25. All identifiers are synthetic. Gold objectives come from OR-Tools CP-SAT on the same schema that ships in each row. LLM rows in `results.jsonl` are explicitly `not_evaluated`.

## Files

- data/problems.jsonl
- data/results.jsonl
- data/leaderboard.csv
- data/splits.json
- data/sample_preview.json
- data/protocol.md
- demo/ — runnable Gradio Space source
- showcase/ — organization static card

## Splits

- development: 60 instances, templates `D-A` / `D-B` / `D-C` with a `SCHEMA_BEGIN` block
- test: 40 instances, templates `T-A` / `T-B` in prose
- interactive: 20 ids listed in `splits.json`

Development and test do not share `(family, template_id)` pairs. Near-duplicate prompt templates are therefore not reused across the split.

## Metrics

Independent validators recompute inventory balance, pack multiples, budget, capacity, assignment uniqueness/eligibility/capacity, and schedule overlap/precedence/release. Optimality gap is reported only when gold status is `optimal`. An unevaluated method is never written as 0.
