Knowledge-Embedded RL Framework for Capacitated Vehicle Routing Problems

other · 2026-05-16

Researchers proposed a unified reinforcement learning framework for generalized capacitated vehicle routing problems (CVRPs). The framework embeds explicit problem-solving knowledge inspired by Route-First Cluster-Second heuristics. It decomposes CVRPs into two subproblems: route-first and cluster-second. Dynamic programming solves the second subproblem, guiding an RL-based constructive solver for the first. This addresses limitations of end-to-end RL approaches that lack explicit knowledge, improving solution quality. The work appears on arXiv as 2605.14416.
