http://cs.williams.edu/~shikha/teaching/spring20/cs256/handouts/Guide_to_Greedy_Algorithms.pdf 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.
