WebGreedy is an example of heuristic (make the best local choice and hope for the optimal global result), but that does not mean heuristics are greedy. There are many heuristics … A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in a reasonable amount of time.
