A Hybrid Memetic Algorithm for Asymmetric Vehicle Routing with Topographic Constraints: Quantifying the Orographic Gap in Mountain Urban Networks
Classical vehicle routing models assume flat, symmetric road networks, yet mountain cities exhibit gravitational asymmetry and steep gradients that invalidate two-dimensional cost estimates and may produce mechanically infeasible routes. This study formalizes the Asymmetric Capacitated Vehicle Routing Problem with Topo...
