Questions tagged [prims-algorithm]

Prim's algorithm is a greedy algorithm which forms minimum spanning tree for the given graph. During execution, Prim's algorithm grows single tree by adding edges to it, unlike Kruskal's algorithm in which there can be multiple minimum spanning trees during execution.

Finding MST after adding a new vertex

Let $G=(V,E)$ which is undirected and simple. We also have $T$, an MST of $G$. We add a vertex $v$ to the graph and connect it with weighted edges to some of the vertices. Find a new MST for the new ...

Minimum spanning tree such that one edge can be minimised

During a computer coding exam, I have encountered such a problem. Given a list of vertexes and edges between the vertexes,and a positive number, D, what is the minimum spanning tree between the ...
