WebDec 9, 2024 · Traveling salesman problem (TSP) is the well studied and well-explored problem of computer science. Due to its application in diverse fields, TSP has been one of the most interesting problems for researchers and mathematicians. Traveling salesman problem – Description WebTo apply the DP technique, we need to find out if TSP can be divided into similar subproblems or not. Let's take the above example. The graph and its cost adjacency matrix is given below: We can observe that the adjacency cost matrix is symmetric. By symmetric, we mean the distance between cities 2 to 3 is the same as cities 3 to 2.
