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 … WebGreedy is said when you aggregate elements one by one to the solution (following some choice strategy) and never backtrack. Example: straight selection sort can be considered a greedy procedure. Heuristic is a generic term that denotes any ad-hoc/intuitive rule used with the hope of improving the behavior of an algorithm, but without guarantee.
