Approximation Algorithms for Quickest Spanning Tree Problems
Let G = (V, E) be an undirected multi-graph with a special vertex root ∈ V , and where each edge e ∈ E is endowed with a length l(e) ≥ 0 and a capacity c(e) > 0. For a pa...

Collective operations for wide-area message passing systems using adaptive spanning trees
Abstract— We propose a method for wide-area message passing systems to perform collective operations using dynamically created spanning trees. In our proposal, broadcasts and red...

Minimum Spanning Tree Problem with Label Selection
In this paper, we study the minimum spanning tree problem for vertex-labeled graphs, where the weights of edges may vary depending on the selection of labels of vertices at both e...
