www.codecademy.com › modules › greedy-algorithmsA greedy algorithm solves an optimization problem by making the best decision at each step. This is known as the locally optimal decision. Greedy algorithms are simple and efficient but are NOT always correct. In order for a greedy algorithm to work, a problem must satisfy: The optimal substructure property; The greedy property

en.wikipedia.org › wiki › Greedy_algorithmA 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. For example, a greedy strategy for the travelling salesman problem is the following heuristic: "At each step of the journey, visit the nearest unvisited city."

www.geeksforgeeks.org › greedy-algorithmsOct 25, 2022 · Greedy is an algorithmic paradigm that builds up a solution piece by piece, always choosing the next piece that offers the most obvious and immediate benefit. So the problems where choosing locally optimal also leads to global solution are the best fit for Greedy. For example consider the Fractional Knapsack Problem.
