Kruskal’s algorithm

Society for Industrial and Applied Mathematics: Finally, other variants of a parallel implementation of Kruskal’s algorithm have been explored. Dynamic programming Graph traversal Tree traversal Search games.

First, it is proved that the algorithm produces a spanning tree. Graph algorithms Search algorithms List of graph algorithms.

Unsourced material may be challenged and removed. The next-shortest edges are AB and BEboth with length 7.

AB is chosen arbitrarily, and is highlighted. This algorithm first appeared in Proceedings of the American Mathematical Societypp. These running times are equivalent because:.

The basic idea behind Filter-Kruskal is to partition the edges in a similar way to quicksort and filter out edges that connect vertices of the same tree to reduce the cost of sorting.


AD and Kruwkal are the shortest edges, with length 5, and AD has been arbitrarily chosen, so it is highlighted. Introduction To Algorithms Third ed. Proceedings of the American Mathematical Society. The edge Krusal has been highlighted in alyoritma, because there already exists a path in green between B and Dso it would form a cycle ABD if it were chosen. The following code is implemented with disjoint-set data structure:. Even a simple disjoint-set data structure such as disjoint-set forests algroitma union by rank can perform O V operations in O V log V time.

If the graph is connected, the forest has a single component and forms a minimum spanning tree.

Kruskal’s algorithm – Wikipedia

The following Pseudocode demonstrates this. Finally, the process finishes with the algorigma EG of length 9, and the minimum spanning tree is found.

Retrieved from ” https: Kruskal’s algorithm is a minimum-spanning-tree algorithm which finds an edge of the least possible weight that connects any two trees in the forest. Introduction to Parallel Computing. Graph algorithms Spanning tree.


Filter-Kruskal lends itself better for parallelization as sorting, filtering, and partitioning can easily be performed in parallel by distributing the edges between the processors [5]. Second, it is proved that the constructed spanning tree is of minimal weight.

If F is the set of edges chosen algofitma any stage of the algorithm, then there is some minimum spanning tree that contains F.

At the termination of the algorithm, the forest forms a minimum spanning forest of the graph. A variant of Kruskal’s algorithm, named Filter-Kruskal, has been described by Osipov et kruskkal. Many more edges are highlighted in red at this stage: From Wikipedia, the free encyclopedia. The process continues to highlight the next-smallest edge, BE with length 7.

Kruskal’s algorithm is inherently sequential and hard to parallelize.
