MM-OptBench: A Solver-Grounded Benchmark for Multimodal Optimization Modeling

arXiv:2605.12154v1 Announce Type: new Abstract: Optimization modeling translates real decision-making problems into mathematical optimization models and solver-executable implementations. Although language models are increasingly used to generate optimization formulations and solver code, existing benchmarks are almost entirely text-only. This omits many optimization-modeling tasks that arise in operational practice, where requirements are described in text but instance information is conveyed t
