WebKruskal's algorithm [1] finds a minimum spanning forest of an undirected edge-weighted graph. If the graph is connected, it finds a minimum spanning tree. (A minimum spanning tree of a connected graph is a subset of the edges that forms a tree that includes every vertex, where the sum of the weights of all the edges in the tree is minimized.

The theorem was conjectured by Andrew Vázsonyi and proved by Joseph Kruskal (1960); a short proof was given by Crispin Nash-Williams (1963). It has since become a prominent example in reverse mathematics as a statement that cannot be proved in ATR0 (a second-order arithmetic theory with a form of arithmetical transfinite recursion), and a finitary application of the theorem gives the existence of the fast-growing TREE function. fai-csodWebP4197 [Picos] Kruskal Reconstruction Tree, programador clic, el mejor sitio para compartir artículos técnicos de un programador. faiblesse zamazentaWebThis is the kruskal reconstruction tree template of dalao pulled from the Internet The basic idea is the same, maintain a similar and find things.
