WebMay 29, 2024 · The Travelling Salesman Problem (TSP) is the most known computer science optimization problem in a modern world. In simple words, it is a problem of finding optimal route between nodes in the graph. The total travel distance can be one of the optimization criterion. For more details on TSP please take a look here. 4. Java Model WebTo solve the TSP using the Brute-Force approach, you must calculate the total number of routes and then draw and list all the possible routes. Calculate the distance of each route and then choose the shortest one—this is the optimal solution. 2. The branch and bound method. This method breaks a problem to be solved into several sub-problems.
