Baseline-Free Policy Optimization for Neural Combinatorial Optimization

Researchers propose Group Relative Policy Optimization (GRPO), a baseline-free training algorithm for neural combinatorial optimization that eliminates the need for maintaining frozen policy copies. Testing on TSP and CVRP benchmarks shows GRPO prevents training collapse seen in standard REINFORCE while achieving competitive solution quality, offering a more stable alternative for routing problem optimization.

Beyond Static Priors: Dynamic Neural Guidance for Large-Scale Ant Colony Optimization

Researchers introduce DyNACO, a neural-guided optimization framework that dynamically adjusts guidance during iterative search processes rather than relying on static priors. The system scales to 100,000-node problem instances and demonstrates performance improvements over existing neural baselines while maintaining computational efficiency.
