This problem is called the Traveling salesman problem (TSP) because the question can be framed like this: Suppose a salesman needs to give sales pitches in four cities. This problem involves finding the shortest closed tour (path) through a set of stops (cities). solved the TSP by clusters, see for example the work of Phienthrakul [11], what hence forth we will named as CTSP (Clustering the Traveling Salesman Problem). 0000000916 00000 n �s��ǻ1��p����օ���^ \�b�"Z�f�vR�h '���z�߳�����e�sR4fb�*��r�+���N��^�E���Ā,����P�����R����T�1�����GRie)I���~�- Travelling Salesman Problem example in Operation Research. 0000013318 00000 n Nevertheless, one may appl y methods for the TSP to find good feasible solutions for this problem (see Lenstra & Rinnooy Kan, 1974).
