WebSep 25, 2024 · Tour construction procedures Nearest neighbor The nearest neighbor algorithm follows a simple greedy procedure where the next city on a tour is simply the nearest city that has not yet been visited. 8 This approach generally gives a tour within 25% of the Held-Karp lower bound. 3 Greedy WebGreedy can be tricky Our greedy solution used the activity with the earliest finish time from all those activities that did not conflict with the activities already chosen. Other greedy approaches may not give optimum solutions to the problem, so we have to be clever in our choice of greedy strategy and prove that we get the optimum solution.
