Abstract: This paper proposes a novel hybrid approach called Multiplex k-shell and Vertex Cover Integrated Independent Set (MKVI) for influence maximization in a multiplex network. Here, the concepts of k-shell decomposition, vertex cover, and independent set are extended to multiplex networks and combined to select influential nodes (seed sets). The average influence spread of the selected seed set is computed by simulating the independent cascade model with three different influence probabilities (p), where the p values are set to 0.01, 0.05, and 0.1. The proposed MKVI reports a dominant average influence spread in comparison to six state-of-the-art approaches: Degree centrality (DC), Betweenness centrality (BC), Eigenvector centrality (EC), K-shell coefficient (KC), Cost-Effective Lazy Forward selection++ (CELF++), and Reverse random walk (RRW), across six datasets: CElegans, Drosophila, CKM-Physicians, CS-Aarhus, EUAir_Multiplex, and Padgett-Florence-Families_Multiplex_Social. MKVI also reports a closer average influence spread to that of multiplex networks using the learning automata (MISM-LA) method while requiring a much smaller seed set size.

Key words: influence maximization, multiplex k-shell decomposition, multiplex vertex cover, multiplex independent set, seed set selection
