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. WebOct 4, 2024 · No TSP experiments were provided, but gap values of the corresponding MST solutions using 16 clusters varied from 3.7 to 10.7%. Valenzuela and Jones (1995) extended Karp's idea by selecting the direction of a cut via a genetic algorithm and by introducing a method to merge the subsolutions.
