F. maximum weight subset
WebJun 13, 2012 · A function F assigns a weight to each link from set A to set B: F:A*B->R. So, for example, F (a_1,b_1)=2 means that the weight of the link between a_1 and b_1 is 2. … WebCorrectness of Algorithm • Set output consists of compatible requests • By construction! • We want to prove our solution is optimal (schedules the maximum number of jobs) • Let be an optimal set of jobs.Goal: show ,i.e., greedy also selects the same number of jobs and thus is optimal • Proof technique to prove optimality: • Greedy always “stays ahead” (or …
