Theoretical Analysis of DomiRank Centrality: Automorphism, Entropy, and Graph Transformations

DomiRank is a node-importance algorithm for unweighted networks, defined by a dynamical-system model whose steady state is governed by a competition-strength parameter, a dominance threshold, and a natural decay rate. We study its intrinsic relations with graph automorphism: vertices mapped to each other by an automorp...

Link prediction in complex networks via fusing node centrality and local similarity indices: a fair-protocol reassessment and parameter design principles

The design rules obtained for the two mechanisms provide a reproducible protocol benchmark and quantitative parameter design principles for the centrality x local-similarity fusion paradigm and provide a reproducible protocol benchmark and quantitative parameter design principles for the centrality x local-similarity f...
