Greedy spectral selection gss python
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.
