5/3 - Approximation Algorithm for a Multiple Depot, Terminal Hamiltonian Path Problem

This paper addresses one variant of the Multiple Depot Terminal Hamiltonian Path Problem (MDTHPP). There are no algorithms available in the literature for any multiple depot variant of the Traveling Salesman Problem (TSP) or Hamiltonian Path Problem (HPP) that has an approximation ratio that is better than 2. This paper presents an algorithm with an approximation ratio of 5/3 for MDTHPP, if and when the costs are symmetric and they satisfy triangle inequality.
