Researchers have developed DualCert, a novel solver for the Traveling Salesman Problem (TSP) that integrates constraint-coupled learning. This method uses degree equations and subtour-elimination constraints to guide learned transitions, ensuring output validity. DualCert demonstrated strong performance on TSP1000 instances, achieving a mean tour-cost gap of 0.0573% from LKH-3 reference tours within an average of 9.55 seconds per instance. The approach also provides verified candidate-graph lower bounds and achieves significant edge-decision coverage. AI
