OptiAgent: End-to-End Optimization Modeling via Multi-Agent Iterative Refinement

Jul 06, 2026

This work proposes a multi-agent collaborative framework that automatically translates natural language descriptions of operations research problems into solvable mathematical models and executable code. To address common modeling challenges—such as semantic misinterpretation, structural flaws, and mathematical inconsistencies—the approach employs specialized agents to extract decision variables and constraints, integrating structured information extraction, iterative self-correction, and a fourfold feedback validation mechanism to achieve end-to-end modeling. Its modular architecture enhances transparency and auditability throughout the modeling process. Evaluated on four standard benchmarks encompassing linear programming (LP), mixed-integer linear programming (MILP), and nonlinear programming, the method achieves state-of-the-art performance on three and demonstrates highly competitive results on the fourth.
