WebWhen the weights are all 1, this problem is identical to the interval scheduling problem we discussed in lecture 1, and for that, we know that a greedy algorithm that chooses jobs in order of earliest ﬁnish time ﬁrstgives an optimal schedule. A natural question is whether the greedy algorithm works in the weighted case too. WebUnweighted Interval Scheduling Review Recall. Greedy algorithm works if all weights are 1. Consider jobs in ascending order of finish time. Add job to subset if it is compatible with previously chosen jobs. Observation. Greedy algorithm can fail spectacularly if arbitrary
