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. WebTemplate for Greedy Algorithm Process jobs in some order. Add next job to the result if it is compatible with the jobs already in the result. Key question: in what order should we process the jobs? Earliest start timeIncreasing order of start time s(i).
