Prim’s algorithm is a greedy algorithm used to find the minimum spanning tree (MST) of a weighted undirected graph. A spanning tree of a graph is a tree that spans all the vertices of the graph, i.e., it is a subgraph that includes all the vertices and is also a tree. A minimum spanning tree is a spanning tree with the minimum total weight among all possible spanning trees of the graph.
Prim’s algorithm has a time complexity of O(E log V), where E is the number of edges and V is the number of vertices in the graph. It is named after the mathematician Robert C. Prim who invented the algorithm in 1957.

FAQs
1. What is Prim’s algorithm?
Prim’s algorithm is a greedy algorithm used to find the minimum spanning tree (MST) of a weighted undirected graph. A minimum spanning tree is a subgraph that includes all vertices and is also a tree, with the minimum total weight among all possible spanning trees of the graph. The time complexity of Prim’s algorithm is O(E log V), where E is the number of edges and V is the number of vertices in the graph.
2. What is the minimum spanning tree (MST) of a graph?
The minimum spanning tree (MST) of a graph is a spanning tree with the minimum total weight among all possible spanning trees of the graph. A spanning tree of a graph is a tree that spans all the vertices of the graph, i.e., it is a subgraph that includes all the vertices and is also a tree.
3. What is a weighted graph?
A weighted graph is a graph in which each edge is assigned a numerical value, called a weight, that represents a cost, distance, or some other measure associated with the edge.
4. How does Prim’s algorithm work?
Prim’s algorithm works by starting with an arbitrary vertex, and adding the nearest vertex to the tree at each step until all vertices are included. At each step, the algorithm chooses the minimum-weight edge that connects the current tree to a vertex not yet in the tree.
5. What are some limitations of Prim’s algorithm?
Some limitations of Prim’s algorithm include its inability to handle negative edge weights and its dependence on the starting vertex. If the starting vertex is not chosen appropriately, the algorithm may result in a non-optimal solution.
