Algorithms 101: How to use graph algorithms

WebThe algorithm terminates when we have added V-1 edges to the set, where V is the number of vertices in the graph. At this point, the set of edges forms the MST. Like Prim's algorithm, Kruskal's algorithm has a time complexity of O(E log E), where E is the number of edges in the graph. This is because sorting the edges takes O(E log E) time, and each edge is … Webgraph theory, branch of mathematics concerned with networks of points connected by lines.

WebThe efficiency of Prim's algorithm can also depend on the distribution of edge weights in the graph. In particular, if the edge weights are uniformly distributed, a simpler algorithm, such as Kruskal's algorithm, may be more efficient. On the other hand, if the edge weights have a skewed distribution, Prim's algorithm may be more efficient.
