Dijkstra’s algorithm is an iterative algorithm that … WebDijkstra's algorithm allows us to find the shortest path between any two vertices of a graph. It differs from the minimum spanning tree because the shortest distance between two vertices might not include all the vertices … the mummy or ramses the damnedWebJun 15, 2014 · Prim's and Dijkstra's both choose a node by finding some node not in a set and bringing it into the set, but they differ in how they adjust the distances. In Prim's algorithm, the distances used are always the minimum distance from any node out of the set to any node inside the set. In Dijkstra's algorithm, the distance is the minimum of the ... the mummy oscar winner

"In computer science, Prim's algorithm (also known as Jarník'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. The algorithm operates by building this tree one vertex at a time, from an arbitrary starting vertex, at each step adding the cheapest possible connection from the tree to another v… " - Dijkstra prim
