A branch and bound algorithm for the porbabilistic traveling salesman problem

The Probabilistic Traveling Salesman Problem (PTSP) is a generalization of the well-known Traveling Salesman Problem (TSP), the main difference is the cities are present with a probability. PTSP is NP-Hard, researches are rather directed towards heuristics for having acceptable solutions. In this paper, we propose an branch and bound algorithm for exact resolution for the PTSP .Estimating the evaluation represents the originality of our paper.
