Edge Modification Criteria for Enhancing the Communicability of Digraphs
Francesca Arrigo, Michele Benzi · SIAM Journal on Matrix Analysis and Applications · 2016
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.
