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. WebApr 12, 2011 · 1. Develop a polynomial algorithm using greedy approach, for solving this problem. Analyze your algorithm in worst case. 2. Prove that your algorithm returns the optimal solution well. 3. Illustrate your algorithm on the following instance: n = 3, r1 = 3, r2 = 4, r3 = 2. This is clearly a homework problem.
