This paper investigates robust and fast consensus of multi-agent systems subject to external attacks. The strategy of connecting neighbor set is proposed to recover the connectivity of the resulting interconnected network, to improve the robustness against next external attacks, and to guarantee...

Infrastructure systems such as power and water supplies make up the cornerstone of modern society which is essential for the functioning of a society and its economy. They become more and more interconnected and interdependent with the development of scientific technology and social economy....

Urban rail transit networks (URTNs) have experienced rapid development and have been receiving much attention recently. In this paper, we comprehensively analyze the topological characteristics of urban rail transit networks, and we find that the average degrees of nodes of urban rail transit...

A novel statistical maximal information coefficient (MIC) that can detect the nonlinear relationships in large data sets was proposed by Reshef et al. (2011), with emphasis being placed on the equitability, which is a very important concept in data exploration. In this paper, an improved...

Clustering is fundamental for using big data. However, AP (affinity propagation) is not good at non-convex datasets, and the input parameter has a marked impact on DBSCAN (density-based spatial clustering of applications with noise). Moreover, new characteristics such as volume, variety,...

Subgraph matching, which belongs to NP-hard, faces significant challenges on a large scale graph with billions of nodes, and existing methods are usually confronted with greater challenges from both stability and efficiency. In this article, a subgraph matching method in a distributed system,...
