WebJul 27, 2024 · Problems faced in Hill Climbing Algorithm. Local maximum: The hill climbing algorithm always finds a state which is the best but it ends in a local maximum because neighboring states have worse values compared to the current state and hill climbing algorithms tend to terminate as it follows a greedy approach. WebAug 27, 2009 · This simple version of hill-climbing algorithms belongs to the gradient methods which search the space of possible solutions in the direction of the steepest gradient.
