Proof: We prove by induction that after k edges are added to T, that T forms a spanning tree of S.As a base case, after 0 edges are added, T is empty and S is the single node {v}. Also, the set S is connected by the edges in T because v is connected to itself by any set of edges. Therefore, T …

Web5.6.3 Example: Linux Scheduling. Modern Linux scheduling provides improved support for SMP systems, and a scheduling algorithm that runs in O(1) time as the number of processes increases. The Linux scheduler is a preemptive priority-based algorithm with two priority ranges - Real time from 0 to 99 and a nice range from 100 to 140. Web2. Scheduling Algorithms: Early work was carried out by Liu and Layland[2] who presented scheduling algorithms for fixed and dynamic tasks. The rate monotonic algorithm was shown to be useful for fixed priority tasks, and the earliest-deadline-first and minimum laxity first algorithms was proved to be useful for dynamically changing tasks.
