Abstract

The invention discloses a complex network synchronization capability optimization method based on a particle swarm algorithm, and the method is characterized in that the method comprises the followingsteps: for a given complex saturated network, under the condition that the coupling strength between network nodes and the total coupling strength are limited, distributing the coupling strength between the nodes by using a particle swarm algorithm, so that the synchronization capability of the network is optimal. The invention further provides a device based on the method. By utilizing the characteristics of the particle swarm algorithm, the synchronization capability of the network can be efficiently optimized.

Description

technical field [0001] The invention relates to a method and a device for optimizing the synchronization capability of a complex network, in particular to a method and a device for optimizing the synchronization capability of a complex network based on a particle swarm algorithm. Background technique [0002] Synchronization is an important dynamic behavior in complex networks. In the past ten years, the synchronization of complex networks has been widely used in the fields of chemistry, transportation, engineering technology, and biotechnology. In actual network applications, when the network scale is large, in order to optimize the synchronization capability of the network, it is necessary to increase the coupling strength between nodes. However, the coupling strength between nodes in the network cannot increase infinitely, that is, it has saturation. For example, when the time-delay cellular neural network needs to complete the synchronization task, the cells in the netw...
