The community structure as a vital property for complex networks contributes a lot for understanding and detecting inherent functions of real networks. However, existing algorithms which are ranging from the optimization-based to model-based strategies still need to be strengthened further in terms of their robustness and accuracy. In this paper, a kind of multi-headed slime molds, Physarum, is used...
Locating the source of diffusion is a challenging problem in complex networks and has great practical significance for restraining rumors propagation and controlling epidemics spreading. An efficient locating method should have a higher locating accuracy with the minimum required information. Although existing locating methods based on observers consider the time delays of edges, they compute the...
MoN was prepared by rare earth Gd thermal-diffused permeation method via solid–gas interface reaction using (NH4)4[NiMo6O24H6]·7H2O (abbreviated as NiMo6) as the precursor. Thermo-gravimetric differential thermal analysis (TG–DTA) was used to study the product’s stability. The results of X-ray diffractometer (XRD) and X-ray photoelectron spectroscopy (XPS) indicate that a new hexagonal crystal MoN...
Multi-objective traveling salesman problem (MOTSP) is an important field in operations research, which has wide applications in the real world. Multi-objective ant colony optimization (MOACO) as one of the most effective algorithms has gained popularity for solving a MOTSP. However, there exists the problem of premature convergence in most of MOACO algorithms. With this observation in mind, an improved...
