Greedy local search

Web• Hill-climbing also called greedy local search • Greedy because it takes the best immediate move • Greedy algorithms often perform quite well 16 Problems with Hill-climbing n State Space Gets stuck in local maxima ie. Eval(X) > Eval(Y) for all Y where Y is a neighbor of X Flat local maximum: Our algorithm terminates if best WebNov 28, 2014 · The only difference is that the greedy step in the first one involves constructing a solution while the greedy step in hill climbing involves selecting a neighbour (greedy local search). Hill climbing is a greedy heuristic. If you want to distinguish an algorithm from a heuristic, I would suggest reading Mikola's answer, which is more precise.
