WebFeb 13, 2024 · Features of Hill Climbing. Greedy Approach: The search only proceeds in respect to any given point in state space, optimizing the cost of function in the pursuit of the ultimate, most optimal solution. Heuristic function: All possible alternatives are ranked in the search algorithm via the Hill Climbing function of AI.
