WebIt is also called greedy local search as it only looks to its good immediate neighbor state and not beyond that. The steps of a simple hill-climbing algorithm are listed below: Step 1: Evaluate the initial state. If it is the goal state, then return success and Stop. Step 2: Loop Until a solution is found or there is no new operator left to apply. Web1.) Best-first Search Algorithm (Greedy Search): Greedy best-first search algorithm always selects the path which appears best at that moment. It is the combination of depth-first search and breadth-first search algorithms. It uses the heuristic function and search. Best-first search allows us to take the advantages of both algorithms.
