Researchers have developed DualCert, a novel solver for the Traveling Salesman Problem (TSP) that integrates constraint-coupled learning. This method uses current degree equations and dynamically separated subtour-elimination constraints (SECs) 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 in under 10 seconds per instance, with verified candidate-graph lower bounds for all instances.
