A$^{2}$utoLPBench: An Auto-Generated, Agent-Friendly LP Benchmark via Inverse-KKT Construction

arXiv:2607.02141v1 Announce Type: new Abstract: Most LP-from-text benchmarks are static datasets of word problems written and labeled by hand. Once such a dataset is released, its size is fixed, its difficulty is fixed, and every problem can leak into the training data of future LLMs. We present \textbf{A$^{2}$utoLPBench}, a benchmark for testing LLM-driven agents on linear programming problems written in plain text. We first pick a feasible point and dual, then write down a problem for which that point is optimal and the objective value is known. The answer is known by construction, with no s

Why this matters
Why now

The proliferation of large language models and the increasing focus on their autonomous capabilities necessitate more robust and leakage-proof benchmarks to measure their effectiveness in complex problem-solving domains.

Why it’s important

This development is crucial for accurately assessing the true problem-solving abilities of AI agents on linear programming tasks, moving beyond static datasets susceptible to data leakage and offering a path to more reliable evaluation.

What changes

The shift from human-generated, static benchmarks to auto-generated, dynamically created ones ensures a continuous and novel supply of evaluation problems for LLM-driven agents.
