The ‘Travelling salesman problem’ is very similar to the assignment problem except that in the former, there are additional restrictions that a salesman starts from his city, visits each city once and returns to his home city, so that the total distance (cost or time) is minimum. The Traveling Salesman Problem (for short, TSP) was born. DWOA for the TSP Problem The TSP is a widespread concerned combinatorial optimization problem, which can be described as: The salesman should pay a visit to m cities in his region and coming back to the start point. %%EOF 0000015202 00000 n vii.

Travelling Salesman Problem (TSP) : Given a set of cities and distances between every pair of cities, the problem is to find the shortest possible route that visits every city exactly once and returns to the starting point. Above we can see a complete directed graph and cost matrix which includes distance between each village. g.!�n;~� 21. Travelling salesman problem belongs to this one. If salesman starting city is A, then a TSP tour in the graph is-A → B → D → C → A . problem of finding such an a priori tour, which is of minimum length in the expected value sense, is defined as a Probabilistic Traveling Salesman Problem (PTSP). As it is not possible to find its solution in definite polynomial time that is why it is considered as one of the NP-hard problem. xref The traveling salesman problem (TSP) Example c( i, i+1) = 1, for i = 1, ..., n - 1 c( n, 1) = M (for some large number M) c(i,j ...
