Beyond Verified Answers: Solver-Informed Self-Distillation for Bootstrapping Operations Research Language Models

SOLID is proposed, a novel framework for self-improving OR language models without verified answers or external evaluators that improves solution accuracy for both general-purpose and OR-tuned models over outcome-only group-relative training.

GraphBU: MILP Instance Generation with Graph-Native Block Units

GraphBU is proposed, a graph-native generator whose basic unit is a local subproblem plus its interface whose basic unit is a local subproblem plus its interface that keeps graph statistics close to the source family, preserves feasibility on most datasets, and improves downstream Predict-and-Search training.
