In this paper, based on Lyapunov function method and stochastic analysis theory, the stability of a class of impulsive stochastic reaction diffusion differential equations is investigated and some new criteria are obtained ensuring the mean square stability of trivial solution. As an application, a class of semi-linear stochastic impulsive reaction diffusion differential equations has been discussed...
With considering two types of bounded activation functions, the global exponential stability in Lagrange sense are considered for Cohen-Grossberg neural networks with time-varying delays and reaction-diffusion terms. By employing appropriate Lyapunov functions, Green formula and inequality techniques, several global exponential attractive sets are given in which all trajectories converge. The obtained...
A hierarchical structure poly-particle swarm optimization (HSPPSO) approach using the hierarchical structure concept of control theory is presented. In the bottom layer, parallel optimization calculation is performed on poly-particle swarms, which enlarges the particle searching domain. In the top layer, each particle swam in the bottom layer is treated as a particle of single particle swarm. The...
