GISMPk is NP-complete even when . Moreover, GISMPk is MaxSNP-complete, i.e., it does not have a PTAS unless P=NP. This can be proved by showing an approximation-preserving reduction from MAX 3-SAT-3 to GISMP2. The following greedy algorithm finds a solution that contains at least 1/2 of the optimal number of intervals: WebNov 18, 2024 · A fundamental problem in the design of wireless networks is to efficiently schedule transmission in a distributed manner. The main challenge stems from the fact that optimal link scheduling involves solving a maximum weighted independent set (MWIS) problem, which is NP-hard. For practical link scheduling schemes, distributed greedy …

Web2 Scheduling Our rst example to illustrate greedy algorithms is a scheduling problem called interval scheduling. The idea is we have a collection of jobs (tasks) to schedule on some machine, and each job jhas a given start time s j and a given nish time f j. If two jobs overlap, we can’t schedule them both. how much are shingles vaccines at walgreens
