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. WebI'll try to rephrase your comment correctly: If you take an optimal solution, you can turn it into the greedy solution by shiting only. Since shifting does not change the number of firemen, we deduce that the greedy solution has exactly as many firemen as some optimal solution. Therefore, the greedy solution is optimal too. $\endgroup$ – the bubble 65WebMar 21, 2024 · The problem should have an optimal substructure: A given problem has Optimal Substructure Property if the optimal solution of the given problem can be obtained by using optimal solutions of its subproblems.
