WebMay 11, 2014 · I'm implementing a simple version of Prim's algorithm in C++ and having some difficulty translating the algorithm to work with my very basic graph implementation. I have a struct for edges as follows: struct edge { int src; int dest; int weight; }; I simply push the edges to a vector in the graph class. WebMar 20, 2024 · 10 Answers. Use Prim's algorithm when you have a graph with lots of edges. For a graph with V vertices E edges, Kruskal's algorithm runs in O (E log V) time and Prim's algorithm can run in O (E + V log V) amortized time, if you use a Fibonacci Heap. Prim's algorithm is significantly faster in the limit when you've got a really dense graph with ...

WebA spanning tree is a sub-graph of an undirected connected graph, which includes all the vertices of the graph with a minimum possible number of edges. If a vertex is missed, then it is not a spanning tree. The edges may or may not have weights assigned to them. The total number of spanning trees with n vertices that can be created from a ...
