WebIt terminates when it reaches a peak value where no neighbor has a higher value. Traveling-salesman Problem is one of the widely discussed examples of the Hill climbing algorithm, in which we need to minimize the distance traveled by the salesman. It is also called greedy local search as it only looks to its good immediate neighbor state and ... WebDec 28, 2011 · Then you have the so called "informed search" such as best-first search, greedy search, a*, hill climbing or simulated annealing. In short, for the best-first search, you use an evaluation function for each node as an estimate of “desirability". The goal of the greedy search is to expand the node which brings you closer to goal.
