Multi-Scenario Cooperative Evolutionary Algorithm for the β-Robust p-Median Problem with Demand Uncertainty

Applied Sciences, 2019
In this paper, we studied the solution approach for the β-robust p-median problem with a large number of scenarios for the uncertain demands. The concept of neighborhood scenarios was introduced to describe the scenarios with a higher similarity than ...

A polyhedral study of the Hamiltonian p-median problem

Electronic Notes in Discrete Mathematics, 2013
Abstract Given an edge-weighted graph G = ( V , E ) , the Hamiltonian p-median problem (HpMP) asks for determining p cycles in G whose total length is minimized such that each node is contained in exactly one cycle. As the travelling salesman problem (TSP) corresponds to the choice p = 1 , the HpMP can be interpreted as a ...
