Dynamic multi‐objective optimisation of complex networks based on evolutionary computation

IET Networks, EarlyView., 2022
Abstract As the problems concerning the number of information to be optimised is increasing, the optimisation level is getting higher, the target information is more diversified, and the algorithms are becoming more complex; the traditional algorithms such as particle swarm and differential evolution are far from being able to deal with this situation ...

Adaptive sliding mode observers in uncertain chaotic cryptosystems with a relaxed matching condition [PDF]

, 2006
We study the performance of adaptive sliding mode observers in chaotic synchronization and communication in the presence of uncertainties. The proposed robust adaptive observer-based synchronization is used for cryptography based on chaotic masking ...

Mapping Model of Chaotic Phase Synchronization [PDF]

, 2005
A coupled map model for the chaotic phase synchronization and its desynchronization phenomenon is proposed. The model is constructed by integrating the coupled kicked oscillator system, kicking strength depending on the complex state variables.

Regularization of Synchronized Chaotic Bursts [PDF]

Physical Review Letters, 2001
The onset of regular bursts in a group of irregularly bursting neurons with different individual properties is one of the most interesting dynamical properties found in neurobiological systems. In this paper we show how synchronization among chaotically bursting cells can lead to the onset of regular bursting.

Synchronization of Cubic Chaotic System

Modern Applied Science, 2010
Adaptive synchronization of two cubic chaotic systems with the same structure and lag synchronization of cubic chaotic systems and logistic maps with different structure are discussed. The theory and numerical simulation shows that the control strategy needs to select right error estimations.
