Researchers have developed a new module called Constraint-Aware Residual Modulation (CARM) to improve the performance of neural routing solvers. Existing solvers often struggle with complex constraints because their state embedding generation mechanisms limit the observation space during attention computation. CARM enhances constraint awareness by adaptively modulating context embeddings with constraint-relevant variables, allowing solvers to better utilize the global observation space. Experiments show that CARM consistently boosts baseline performance, particularly in scaling to large instances and generalizing to unseen vehicle routing problem variants. AI
