Prim's Algorithm is a fundamental concept in graph theory, used to construct the minimum spanning tree (MST) of a weighted, undirected graph. It employs a greedy approach, starting from an initial vertex and adding the lowest-weight edges without forming cycles. This algorithm is crucial for network design, logistics, and civil engineering, optimizing costs and resources efficiently.

Origin and Contributors
Prim's Algorithm was first presented by Czech mathematician Vojtěch Jarník in 1930 and later brought to prominence by computer scientist Robert C. Prim in 1957
Greedy Approach and Performance
Prim's Algorithm exemplifies a greedy approach, starting from a selected initial vertex and progressively adding the lowest-weight edge to find the minimum spanning tree with optimal performance
Prim's Algorithm operates on a weighted, connected, undirected graph and uses a priority queue data structure to efficiently select the next edge to add to the minimum spanning tree
Prim's Algorithm adds the lowest-weight edge connecting two sets of vertices, moving the respective vertex to the included set, until all vertices are included in the minimum spanning tree
