MaxDDBS problem on butterfly networks

A maximum degree-diameter bounded subgraph problem can be seen as a degree-diameter problem restricted to certain host graphs. In this paper, we investigate the MaxDDBS problem when the host graph is a butterfly network. We give constructive lower bounds for subgraphs of maximum degree 4, 3 and 2. ∗ Was also at Department of Mathematics, University of West Bohemia, Pilsen, Czech Republic. Deceased January 2016. N.H.
