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 can be tricky Our greedy solution used the activity with the earliest finish time from all those activities that did not conflict with the activities already chosen. Other greedy approaches may not give optimum solutions to the problem, so we have to be clever in our choice of greedy strategy and prove that we get the optimum solution.
