Prim's does not evaluate the total weight of the path from the starting node, only the individual path. "Dijkstra is concerned with only two nodes" is bunk.

WebOct 10, 2024 · The goal of Dijkstra’s algorithm is to conduct a breadth-first search with a higher level of analysis in order to find the shortest path between two nodes in a graph. Here’s how it works: Pick the start and end nodes and add the start node to the set of solved nodes with a value of 0.
