WebFeb 14, 2024 · As we mentioned earlier, the Greedy algorithm is a heuristic algorithm. We are going to use the Manhattan Distance as the heuristic function in this tutorial. The Greedy algorithm starts from a node (initial state), and in each step, chooses the node with the minimum heuristic value, which is the most promising for the optimum solution.
