It switches to forwarding on a spanning tree only to route packets around voids, and escape from a local minimum.[11] It switches back to greedy forwarding as soon as it is feasible to do so.

It’s curious to say that the algorithm developed by Robert Prim isn’t developed by him. It’s considered that a Czech mathematician discovered back in 1930. However now we know this algorithm as the algorithm of Prim, which independently discovered it in 1957 as I said above, and finally described it in 1959. That’s why his algorithm on finding the single-source shortest paths in a graph looks so much to this algorithm. Perhaps by finding this algorithm on minimum spanning tree Dijkstra discovered how we can find the shortest paths to all vertices using a priority queue. Indeed the paths to all other vertices use the edges of the minimum spanning tree.

As we already know the algorithm of Kruskal works in a pretty natural and logical way. Since we’re trying to build a MST, which is naturally build by the minimal edges of the graph (G), we sort them in a non-descending order and we start building the tree.

As the output of the algorithm, every node knows which of itslinks belong to the Minimum Spanning Tree and which do not.

This paper presents a randomized Las Vegas distributed algorithm thatconstructs a minimum spanning tree (MST) in weighted networks withoptimal (up to polylogarithmic factors) time and message complexity.

Distributed minimum spanning tree - Revolvy

The problem of verifying a Minimum Spanning Tree (MST) was introduced by Tarjan in a sequential setting. Given a graph and a tree that spans it, the algorithm is required to check whether this tree is an MST. This paper investigates the problem in the distributed setting, where the input is given in a distributed manner, i.e., every node “knows ” which of its own emanating edges belong to the tree. Informally, the distributed MST verification problem is the following. Label the vertices of the graph in such a way that for every node, given (its own label and) the labels of its neighbors only, the node can detect whether these edges are indeed its MST edges. In this paper we present such a verification scheme with a maximum label size of O(log n log W), where n is the number of nodes and W is the largest weight of an edge. We also give a matching lower bound of Ω(log n log W) (except when W ≤ log n). Both our bounds improve previously known bounds for the problem. Our techniques (both for the lower bound and for the upper bound) may indicate a strong relation between the fields of proof labeling schemes and implicit labeling schemes. For the related problem of tree sensitivity also presented by Tarjan, our method yields rather efficient schemes for both the distributed and the sequential settings.

We use the following API for computing an MST of an edge-weightedgraph:
We prepare some test data:Prim's algorithm works by attaching a new edge to a single growing tree at each step:Start with any vertex as a single-vertex tree; then add V-1 edges toit, always taking next (coloring black) the minimum-weight edge thatconnects a vertex on the tree to a vertex not yet on the tree(a crossing edge for the cut defined by tree vertices).

If a graph is not connected, we can adapt our algorithms to computethe MSTs of each of its connected components, collectively known as aminimum spanning forest.
