There are two minimum spanning tree algorithms. One is prim algorithm and the other is Kruskal algorithm. The time complexity of the two algorithms are o (n^2) and O (mlogn) [n is the number of points and m is the number of edges]. The two algorithms behave differently in different graphs. Let's start with prim algorithm. The core idea of thi ...

Classification of minimum spanning tree 🐖: The minimum spanning tree is generally used for undirected graphs, and directed graphs are rarely used. Method selection: Dense graph: using naive Prim algorithm Sparse graph: using Kruskal algorithm Heap optimized Prim is not commonly used! Plain Prim The general idea can be referred to Dijk ...
