WebThe Multiple Traveling Salesman Problem (mTSP) is a generalization of the Traveling Salesman Problem (TSP) in which more than one salesman is allowed. Given a set of cities, one depot where (m) salesmen are located, and a cost metric, the objective of the (m)TSP is to determine a tour for each salesman such that the total tour cost is minimized and that … WebTime windows and synchronization are given as patients' availability preferences and caregivers' synchronization.
