New framework improves large-scale vehicle routing by enabling subproblem collaboration

Researchers have developed a new framework called Collaborative Routing Constructors (CoRC) to address challenges in large-scale Capacitated Vehicle Routing Problems (CVRPs). Traditional methods partition customers into smaller, independently optimized problems, which can lead to unserved demand. CoRC allows these subproblems to exchange customers and vehicles during optimization, ensuring more robust and feasible solutions. Experiments show CoRC consistently produces feasible routes where other partition-based methods fail and remains effective even when other advanced frameworks do not find solutions within the same computational budget.
