Learn2Aggregate: Supervised Generation of Chvatal-Gomory Cuts Using Graph Neural Networks
AAAI 2025technical
We present Learn2Aggregate, a machine learning (ML) framework for optimizing the generation of Chvatal-Gomory (CG) cuts in mixed integer linear programming (MILP). The framework trains a graph neural network to classify useful constraints for aggregation in CG cut generation. The ML-driven CG separa…
