# SLR-Bench

SLR-Bench is a benchmark for scalable logical reasoning with language models. The tasks require generating Prolog rules that correctly classify trains based on their compositions.

### Paper

Title: `SLR: Automated Synthesis for Scalable Logical Reasoning`

Abstract: [https://arxiv.org/abs/2506.15787](https://arxiv.org/abs/2506.15787)

### Dataset

The complete dataset can be found at:
[https://huggingface.co/datasets/AIML-TUDA/SLR-Bench](https://huggingface.co/datasets/AIML-TUDA/SLR-Bench)

### Verifier

- Generated rules are evaluated using a symbolic verifier (`AIML-TUDA/VerifiableRewardsForScalableLogicalReasoning`).

###  Automated Synthesis Framework to Generate new Tasks

## Prerequisites

- **SWI-Prolog**: Required for evaluating generated rules. Make sure `swipl` is installed and available in your system PATH.

#### Tasks

The following variants are available:

- `slr_bench_all` &mdash; Full dataset (`v1-All`)
- `slr_bench_basic` &mdash; Basic subset (`v1-Basic`)
- `slr_bench_easy` &mdash; Easy subset (`v1-Easy`)
- `slr_bench_medium` &mdash; Medium subset (`v1-Medium`)
- `slr_bench_hard` &mdash; Hard subset (`v1-Hard`)
