WebNov 9, 2024 · The binary heap data structure allows us to extract-min (remove the node with minimal ) and update an element (recalculate ) in time. Therefore, the time complexity becomes , which is , since as is a connected graph. For a more in-depth overview and implementation of the binary heap, we can read the article that explains Priority Queue. WebPrim's algorithm is another popular minimum spanning tree algorithm that uses a different logic to find the MST of a graph. Instead of starting from an edge, Prim's algorithm starts from a vertex and keeps adding lowest-weight edges which aren't in the tree, until all vertices have been covered. Kruskal's Algorithm Complexity
