WebGiven a graph G ( V, A), we know that any spanning tree contains an edge in every cutset. Let S m i n m a x and S be the minimax weight spanning tree of G and minimum weight spanning tree of G resp. Any edge e ∈ S is associated with a cutset C. Corresponding to cutset C, S m i n m a x must also contain an edge, say e ′. Web5 apr. 2024 · Algorithm. Step 1 − First, we need to import the fmt and math package. Then define a struct node. Initialize the distance and visited arrays. Step 2 − Set the distance of the source vertex to 0 and push it into the priority queue. Step 3 − While the priority queue is not empty, extract the vertex with the minimum distance from the queue.
