New OD-Gear framework tackles large-scale vehicle routing problems

Researchers have developed OD-Gear, a novel expert-guided adversarial framework designed to tackle large-scale capacitated vehicle routing problems (CVRP). This framework integrates hybrid genetic search and online barycenter clustering with a graph attention network (GAT) policy, enhanced by knowledge distillation and minimax adversarial training. OD-Gear aims to provide high-quality, clustering-free inference for massive datasets, demonstrating state-of-the-art performance on most benchmarks and maintaining competitiveness at the 10,000-node scale.
