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. WebOct 25, 2024 · This results in the following 1-tree: With this we obtain a lower bound of ~113139 which brings us to nearly 96% of the optimal tour. It also only takes about 2.5ms to compute this lower bound. This means we can do quite some more stuff before we reach the 8s from the current approach.
