When Greedy Algorithms are Perfect: the Matroid

WebGreedy algorithms tend to be made up of five components. These components include: A candidate set from which a solution is created. A selection function, which picks the best candidate that will be added to the solution. A feasibility function. This is used to determine whether a candidate can be used to contribute to a solution.

WebFeb 23, 2024 · A Greedy algorithm is an approach to solving a problem that selects the most appropriate option based on the current situation. This algorithm ignores the fact that the current best result may not bring about the overall optimal result. Even if the initial decision was incorrect, the algorithm never reverses it.
