This observation gives us a nonrecursive algorithm for finding minimum-cost spanning trees on mesh-connected computers which has the same asymptotic running time as but is much simpler than the previous recursiv
Minimum spanning tree is the spanning tree where the cost is minimum among all the spanning trees. There also can be many minimum spanning trees. Minimum spanning tree has direct application in the design of networks. It is used in algorithms approximating the travelling salesman problem, multi...

Two parallel algorithms are presented for solving the minimum cost spanning tree problem in any undirected graph. These algorithms are parallel formulations of DHEA algorithm using Depth-First Search of the graph. The cost-optimality of both algorithms are investigated.doi:10.1080/00207160210945...
Prim's algorithm to find minimum cost spanning tree (as Kruskal's algorithm) uses the greedy approach. Prim's algorithm shares a similarity with the shortest path first algorithms. Prim's algorithm, in contrast with Kruskal's algorithm, treats the nodes as a single tree and keeps on adding ...

We consider an extension of minimum cost spanning tree (mcst) problems in which some agents do not need to be connected to the source, but might reduce the cost of others to do so. Even if the cost usually cannot be computed in polynomial time, we extend the characterization of the Kar...
Assume that a connected undirected edge weighted graphGis given. The Degree Constrained Minimum Spanning Tree Problem (DCMSTP) asks for a minimum cost spanning tree ofGwhere vertex degrees do not exceed given pre-defined upper bounds. In this paper, three exact solution algorithms are investigated ...
