New ECpM problem formulation optimizes road network partitioning

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a new problem formulation called the edge-based contiguous p-median (ECpM) problem, designed to partition road networks into compact and contiguous territories. The paper presents two binary programming models to address this, one using a branch-and-cut algorithm with exponential constraints and another employing a polynomial number of shortest-path constraints solvable by standard solvers. The latter approach demonstrated significant speedups, achieving up to 17x faster computation times on large road networks compared to the cut set-based method. AI

    The Edge-based Contiguous p-median Problem with Connections to Logistics Districting

    arXiv:2608.11230v1 Announce Type: new Abstract: This paper introduces the edge-based contiguous p-median (ECpM) problem to partition the roads in a network into a given number of compact and contiguous territories. Two binary programming models are introduced, both of which incor…
