WebJul 17, 2024 · Greedy algorithms are simple, intuitive, small, and fast because they usually run in linear time (the running time is proportional to the number of inputs provided). Unfortunately, they don't offer the best solution for all problems, but when they do, they provide the best results quickly. WebElements of the greedy strategy A greedy algorithm obtains an optimal solution to a problem by making a sequence of choices. For each decision point in the algorithm, the choice that seems best at the moment is chosen. This heuristic strategy does not always produce an optimal solution, but as we saw in the activity- selection problem ...
