Feb 9, 2024 · The time complexity of Prim's algorithm is O(V 2) using an adjacency matrix and O((V +E) log V) using an adjacency list, where V is the number of vertices and E is the number of edges in the graph. The space complexity is O(V+E) for the priority queue and O(V 2 ) for the adjacency matrix representation.

Feb 26, 2025 · Prim’s algorithm is guaranteed to find the MST in a connected, weighted graph. It has a time complexity of O ( (E+V)*log (V)) using a binary heap or Fibonacci heap, where E is the number of edges and V is the number of vertices. It is a relatively simple algorithm to understand and implement compared to some other MST algorithms. Disadvantages:

In computer science, Prim's algorithm is a greedy algorithm that finds a minimum spanning tree for a weighted undirected graph. This means it finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is minimized.

Feb 27, 2025 · Prim’s algorithm is a key method in data structure used to find the Minimum Spanning Tree (MST) of a graph. This algorithm works by starting with a single node and gradually adding the smallest possible edges that connect new nodes to the tree.

The time complexity of Prim's algorithm is O(VlogV + ElogV). It seems like you understand how the VlogV came to be, so let's skip over that. So where does ElogV come from?

Prim's algorithm finds the Minimum Spanning Tree (MST) in a connected and undirected graph. The MST found by Prim's algorithm is the collection of edges in a graph, that connects all vertices, with a minimum sum of edge weights. Prim's algorithm finds the MST by first including a random vertex to the MST.

Apr 22, 2023 · Prim’s algorithm is a greedy algorithm that starts with a single vertex and adds one edge at a time to form a tree. This means it finds a subset of the edges that forms a tree that includes...

Oct 30, 2012 · Prim's Algorithm is an algorithm that takes a graph and a starting node, and finds a minimum spanning tree on the graph - that is, it finds a subset of the edges so that the result is a tree that contains all the nodes and the combined edge weights are minimized. It may be summarized as follows:

Here’s how Prim’s Algorithm behaves in sparse graphs: Number of edges: In a sparse graph, the number of edges (E) is approximately O(V). Using an adjacency list: If you use an adjacency list, finding the minimum edge can be done in O(E) time. Overall complexity: The overall time complexity becomes O(E log V) when using a priority queue.
