Reports Outline Physics Research Study Findings from Korea University (Network robustness of multiplex networks with interlayer degree correlations)

July 29, 2014

By a News Reporter-Staff News Editor at Physics Week -- Investigators publish new report on Physics Research. According to news reporting out of Seoul, South Korea, by VerticalNews editors, research stated, "We study the robustness properties of multiplex networks consisting of multiple layers of distinct types of links, focusing on the role of correlations between degrees of a node in different layers. We use generating function formalism to address various notions of the network robustness relevant to multiplex networks, such as the resilience of ordinary and mutual connectivity under random or targeted node removals, as well as the biconnectivity."

Our news journalists obtained a quote from the research from Korea University, "We found that correlated coupling can affect the structural robustness of multiplex networks in diverse fashion. For example, for maximally correlated duplex networks, all pairs of nodes in the giant component are connected via at least two independent paths and network structure is highly resilient to random failure."

According to the news editors, the research concluded: "In contrast, anticorrelated duplex networks are on one hand robust against targeted attack on high-degree nodes, but on the other hand they can be vulnerable to random failure."
