Webalgorithm. We introduce it with the greedy algorithms for minimum makespan scheduling and multiway cut problems in this lecture. 3.2 Minimum Makespan Scheduling A central problem in scheduling theory is to design a schedule such that the last nishing time of the given jobs (also called makespan) is minimized. This problem is called the minimum ... 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
