WebA given optimal substructure property if the optimal solution of the given problem can be obtained by finding the optimal solutions of all the sub-problems. In other words, we can solve larger problems given the solution of smaller problems. Suppose we have given a complex problem, then we will break this problem into simpler problems optimally ... 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.

(We'll get to that later.) But then Johnson had a bright idea in 1977 that salvaged the greedy approach. dallas smith concert tourhttp://duoduokou.com/algorithm/50867821092277819463.html dallas smith lawyer reginaWebFloyd's or Floyd-Warshall Algorithm is used to find all pair shortest path for a graph.
