A Hierarchical Grouping Algorithm for the Multi-Vehicle Dial-a-Ride Problem
Summary: Introduces HGR, the first non-trivial approximation algorithm for the Multi-Vehicle Dial-a-Ride Problem via a reduction to a capacitated partitioning problem solved by a novel hierarchical grouping scheme. Empirically yields lower total travel distance and reduced in-transit latency versus baselines. (summarized by gpt-5-mini on Feb 09 2026)
