INTRODUCTION Travelling Salesman Problem TSP first expressed as computational mathematics problem in 1930. He starts in his home city A and then needs to travel to several different cities to sell his wares the other cities are B C D etc. TSP belongs to the category of NP hard problems. Mathematicians call this the quot traveling salesman problem quot in which scientists try to calculate the shortest possible route given a theoretical arrangement of cities. Solving the traveling salesman problem using the branch and bound method. Available online May 2014. Given the solution to the TSP can be represented by a vector of integers in the range 0 to n 1 we could define a discrete state optimization problem object and use one of mlrose s randomized optimization algorithms to solve it as we did This software is intended to generate and solve Travelling Salesman Problem TSP tasks. Say it is T 1 2 3 4 means initially he is at village 1 and then he can go to any of 2 3 4 . Many exact and heuristic algorithms Ever since the early days of discrete optimization the traveling salesman problem has served as the model for computationally hard problems. In this section we introduce the Travelling Salesman Problem and the Ant Colony Optimization algorithm. 18. 4 June 1994 By Charles Arthur.
