Prim's Algorithm is a specialized graph traversal algorithm used to find minimum spanning trees, or the subgraphs connecting all nodes in a connected, weighted graph with the least possible total edge weight, similar to Kruskal's Algorithm. Prim's Algorithm starts with an empty spanning tree. It then grows the tree by adding one edge at a time, until all vertices are included. The edge added at each step is the lowest-weight edge that connects a vertex in the tree to a vertex not yet in the tree.

Prim's Algorithm starts with an empty spanning tree. It then grows the tree by adding one edge at a time, until all vertices are included. The edge added at each step is the lowest-weight edge that connects a vertex in the tree to a vertex not yet in the tree.
To run Prim's Algorithm, we start by selecting any vertex in the graph as the initial vertex.
The algorithm then works as follows:
Consider the following graph with 7 vertices and 11 edges:
If we start Prim's Algorithm at node A, we would get the following minimum spanning tree with total edge weight of 39:
There are a few variations of Prim's Algorithm:
Prim's Algorithm is a topic covered in many online courses. These courses teach the basics of Prim's Algorithm, as well as its variations and applications. Some of the skills and knowledge that you can gain from these courses include:
Online courses can be a great way to learn Prim's Algorithm and other graph algorithms. They provide a flexible and affordable way to learn at your own pace.
Whether or not online courses are enough to fully understand Prim's Algorithm depends on your individual learning style. If you are a self-motivated learner who is able to learn independently, then online courses may be sufficient.
However, if you prefer a more structured learning environment, then you may want to consider taking a traditional in-person course. In-person courses offer the opportunity to interact with an instructor and classmates, which can be helpful for understanding complex topics.
Prim's Algorithm is a versatile graph traversal algorithm that can be used to solve a variety of problems. It is a relatively simple algorithm to implement and understand, making it a good choice for beginners. If you are interested in learning more about Prim's Algorithm, there are many online courses available that can teach you the basics.
