WebDec 21, 2024 · The greedy algorithm works in phases, where the algorithm makes the optimal choice at each step as it attempts to find the overall optimal way to solve the entire problem. [2] It is a technique used to solve the famous “traveling salesman problem” where the heuristic followed is: "At each step of the journey, visit the nearest unvisited city." WebChapter 16: Greedy Algorithms Greedy is a strategy that works well on optimization problems with the following characteristics: 1. Greedy-choice property: A global optimum can be arrived at by selecting a local optimum. 2. Optimal substructure: An optimal solution to the problem contains an optimal solution to subproblems. The second property ...
