Edge modification criteria for enhancing the communicability of digraphs (1508.01056v2)
Published 5 Aug 2015 in cs.SI, math.NA, and physics.soc-ph
Abstract: We introduce new broadcast and receive communicability indices that can be used as global measures of how effectively information is spread in a directed network. Furthermore, we describe fast and effective criteria for the selection of edges to be added to (or deleted from) a given directed network so as to enhance these network communicability measures. Numerical experiments illustrate the effectiveness of the proposed techniques.
