Greedy scheduling algorithm

WebA greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. [1] 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. WebMar 8, 2024 · The second kind of task scheduling algorithm is based on the greedy strategy [13,14,15,16]. When solving a problem, it always makes what seems to be the best choice at the moment. In other words, instead of finding the global optimum, what it does is in some sense the local optimal solution. Greedy algorithm is not the overall optimal …
