An Amortized Efficiency Threshold for Comparing Neural and Heuristic Solvers in Combinatorial Optimization
Researchers have developed WeCon, a novel neural solver designed to efficiently tackle multi-objective combinatorial optimization problems. This new approach improves upon existing methods by enhancing the interaction between problem instance features and weight vectors during both encoding and decoding phases. WeCon also introduces an efficient preference optimization technique to generate more informative training data, leading to improved effectiveness. Experiments show WeCon achieves comparable results to state-of-the-art solvers while significantly reducing inference time. AI
