Algorithm for Traveling salesman problem. Step 1: Let d [i, j] indicates the distance between cities i and j. Function C [x, V – { x }]is the cost of the path starting from city x. V is the set of cities/vertices in given graph. The aim of TSP is to minimize the cost function. Step 2:. Traveling Salesman Problem. The TSP involves finding the minimum traveling cost for visiting a fixed set of customers. The vehicle must visit each customer exactly once and return to its point of origin also called depot.
