It has combined features of UCS and greedy best-first search, by which it solve the problem efficiently. It finds the shortest path through the search space using the heuristic function. This search algorithm expands fewer search tree and gives ... 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). rdwithit
