Greedy best first search vs hill climbing

WebHill climbing. A surface with only one maximum. Hill-climbing techniques are well-suited for optimizing over such surfaces, and will converge to the global maximum. In numerical … WebSimilar to Greedy Best-First search but Hill-Climbing does not allow backtracking or jumping to an alternative path since there is no nodes list of other candidate frontier nodes from which the search could be continued. Corresponds to Beam search with a beam width of 1 (i.e., the maximum size of the nodes list is 1).
