Abstract
In this paper, we consider the clustered path travelling salesman problem. In this problem, we are given a complete graph \(G=(V,E)\) with edge weight satisfying the triangle inequality. In addition, the vertex set V is partitioned into clusters \(V_1,\cdots ,V_k\). The objective of the problem is to find a minimum Hamiltonian path in G, and in the path all vertices of each cluster are visited consecutively. We provide a polynomial-time approximation algorithm for the problem.
