Greedy algorithm design technique
WebAlgorithm Design Techniques Over the years computer scientists have identified a number of general techniques that often yield effective algorithms in solving large classes of problems. This chapter presents some of the more important techniques, such as divide-and-conquer, dynamic programming, greedy techniques, backtracking, and local search. 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.
