Complexity of greedy algorithm

WebA greedy algorithm is an approach for solving a problem by selecting the best option available at the moment. It doesn't worry whether the current best result will bring the overall optimal result. The algorithm never reverses the earlier decision even if the choice is wrong. It works in a top-down approach. This algorithm may not produce the ... WebMar 20, 2024 · The employment of “greedy algorithms” is a typical strategy for resolving optimisation issues in the field of algorithm design and analysis. These algorithms aim to find a global optimum by making locally optimal decisions at each stage. The greedy algorithm is a straightforward, understandable, and frequently effective approach to ...
