Web2 / 4 Theorem (Feasibility): Prim's algorithm returns a spanning tree. 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 … WebApr 2, 2024 · For example, a common division is made between foreground (interactive) processes and background (batch) processes. These two types of processes have …
