The greedy schedule has no idle time. d j 6 t j 3 1 8 2 2 9 1 3 9 4 4 14 3 5 15 2 6 time required deadline job number 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 ...
WebGreedy Algorithm- Greedy Algorithm is adopted to determine how the next job is selected for an optimal solution.
