WebAug 3, 2024 · What Is A Greedy Algorithm? In these algorithms, we aim to achieve a local maximum/minimum at each step in order to achieve a global maximum/minimum in the end. That is, we maximize/minimize the answer to each of the subproblems and it leads us to the maximum/minimum answer of the overall problem. how fast is the itali rsx
