# FindStatBench

FindStatBench evaluates whether a model can turn a mathematical description into a Python function, `solve(obj)`, that computes a statistic or maps one combinatorial object to another. The corpus contains **2,329 tasks** in **24 collections** and **5,517,046 evaluation instances** held out from generation prompts.

This Parquet distribution, version **1.0.0-hf1**, preserves the original task records, closed-book prompts, and evaluation instances without changing their values or order. See the [paper](https://arxiv.org/abs/2607.18260) for the evaluation protocol and the [Zenodo archive](https://doi.org/10.5281/zenodo.20060361) for the historical evaluator and experiment artifacts.

## Configurations

| Configuration | Rows | Contents |
|---|---:|---|
| `prompts` (default) | 2,329 | Exact model-facing closed-book prompts and task IDs |
| `tasks` | 2,329 | Task metadata, public examples, and original source-bearing task prompts |
| `hidden` | 5,517,046 | Evaluation inputs and reference outputs, withheld from model prompts |

All configurations have a single `test` split. The corpus includes 1,993 statistic tasks (1,929,082 evaluation instances) and 336 map tasks (3,587,964 evaluation instances).

## Loading the data

```python
from datasets import load_dataset

repo_id = "sdan021/FindStatBench"
prompts = load_dataset(repo_id, "prompts", split="test")
evaluation = load_dataset(repo_id, "hidden", split="test", streaming=True)
```

For the one-shot protocol, send only the `prompt` field from the `prompts` configuration. The `tasks.prompt` field is a source-bearing archival prompt, not the input for closed-book generation. The evaluation labels are publicly downloadable; they must not be used for training, retrieval, feedback, or candidate selection when reporting closed-book scores. Report public-example repair and any other tool use or selection separately.

Nested fields in the task and evaluation tables are encoded as JSON strings in columns ending in `_json`. This preserves strings such as binary words with leading zeros. The MIT-licensed `findstatbench_data.py` helper decodes those fields without changing the records. Record the repository revision for reproducibility. `package_manifest.json` records source and shard checksums and canonical record digests.

## Evaluation and limitations

Use the historical evaluator in the [Zenodo archive](https://doi.org/10.5281/zenodo.20060361) for comparison with the paper. Run untrusted generated programs only in an isolated execution environment. An extracted program can fail to run or be incorrect. Report task accuracy (all cases correct for a task) and instance accuracy (fraction of cases correct) separately.

Some inputs and map targets retain normalized string encodings. Exact scoring can reject mathematically equivalent outputs in other representations. Public source pages, retained cross-references, and downloadable labels mean this benchmark cannot establish that a model has never seen a task. Finite tests are not a proof of correctness, and these results are not a measure of general software engineering.
