WebYou should know that there are many cases where greedy algorithms are, in principle alone, not capable of finding the global optimum. Not for the problem we’re here to talk about though! As it turns out, there exists a greedy algorithm to solve the interval scheduling problem that can be proven to always find the optimal solution. Web– Greedy modify the solution: Say ' 5is the event with the earliest finish time ( ' 5is the first greedy choice) – Let 1 5be a legal schedule that does not include ' 5 – Claim: there is a schedule O′ that does include ' 5such that ’ R 1 5 – Proof: (greedy modify the solution)
