The traveling salesman problem can be divided into two types: the problems where there is a path between every pair of distinct vertices (no road blocks), and the ones where there are not (with road blocks). Mampu memahami dan menerapkan algoritma dynamic project, We consider the combinatorial optimization problem of visiting clusters of a fixed number of nodes (cities) under the special type of precedence constraints. We can observe that cost matrix is symmetric that means distance between village 2 to 3 is same as distance between village 3 to 2. This modification could result in an optimal. Clearly starting from a given city, the salesman will have a, sequences. In any case, the model serves to illustrate how problems of this sort may be succinctly formulated in integer programming terms. In this paper, transportation problem in fuzzy environment using trapezoidal fuzzy number is discussed. Sharma J. K., Operation research theory and application, Third Edition, 2007.

Abstract The Traveling Salesman Problem with Pickup and Delivery (TSPPD) describes the problem of nding a minimum cost path in which pickups precede their associated deliveries. The solution procedure is illustrated with the existing Stephen Dinegar.D &. The moving-target traveling salesman problem ... based on a mixed integer linear programming formulation and dynamic programming [9,10,12]. It demands very elegant formulation of the approach and, simple thinking and the coding part is very easy. Hong, M. Jnger, P. Miliotis, D. Naddef, M. Padberg, W. Pulleyblank, G. Reinelt, and G. George B. Dantzig is generally regarded as one of the three founders of linear programming, along with von Neumann and Kantorovich. This paper addresses the TSP using a new approach to calculate the minimum travel cost Dynamic programming approaches have been Key Words: Travelling Salesman problem, Dynamic Programming Algorithm, Matrix . Zadeh L.A., Fuzzy sets Information and Control, 8, 3, 338-353, 1965. We show that the traveling salesman problem with a symmetric relaxed Monge matrix as distance matrix is pyramidally solvable and can thus be solved by dynamic programming. A traveler needs to visit all the cities from a list, where distances between all the cities are known and each city should be visited just once. For the general TSP without ad-ditional assumptions, this is the exact algorithm with the best known worst-case running time to this day (Applegate et al., 2011). Given a set of cities(nodes), find a minimum weight Hamiltonian Cycle/Tour. search theory and application, Third Edition, 2007. http://www.mafy.lut.fi/study/DiscreteOpt/tspdp.pdf.
