Fixed Parameter Evolutionary Algorithms and Maximum Leaf Spanning Trees: A Matter of Mutation
Abstract. Evolutionary algorithms have been shown to be very successful for a wide range of NP-hard combinatorial optimization problems. We investigate the NP-hard problem of compu...

On Variants of the Spanning Star Forest Problem
A star forest is a collection of vertex-disjoint trees of depth at most 1, and its size is the number of leaves in all its components. A spanning star forest of a given graph G is ...

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...
