A demo for Prim's algorithm based on Euclidean distance. 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. The ...
An animation of generating a 30 by 20 maze using Prim's algorithm. This algorithm is a randomized version of Prim's algorithm. Start with a grid full of walls. Pick a cell, mark it as part of the maze. Add the walls of the cell to the wall list. While there are walls in the list: Pick a random wall from the list.
[8] [9] Bader and Cong presented an MST-algorithm, that was five times quicker on eight cores than an optimal sequential algorithm. [ 10 ] Another challenge is the External Memory model - there is a proposed algorithm due to Dementiev et al. that is claimed to be only two to five times slower than an algorithm that only makes use of internal ...

A planar graph and its minimum spanning tree. Each edge is labeled with its weight, which here is roughly proportional to its length. A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight. [1]
The algorithm starts by choosing the cheapest edge out of A, then choosing the cheapest edge between {A,D} and {B,C} (there are two of weight 2, and BD is chosen arbitrarily). In the next step the edge AB is no longer a candidate because it now joins two nodes already in the tree, and the only edge remaining to be added is CD.
No, there is nothing wrong with this example. Just because A is the first letter in the alphabet does not mean you have to start with A. In fact, I think starting from D is more instructive because it demonstrates the arbitrariness. As an expert in Prim's algorithm, I feel confident this is the case and have removed the cleanup tag.
