Review of harmony search with respect to algorithm structure

T Zhang, ZW Geem - Swarm and Evolutionary Computation, 2019 - Elsevier
… In practice, the HM matrix (3) is a sorted matrix according to the fitness of the objective
function, for example, Ingram & Zhang [10] suggested to store the best solution vector in the first …

The spatially inhomogeneous Hopf bifurcation induced by memory delay in a memory-based diffusion system

Y Song, Y Peng, T Zhang - Journal of Differential Equations, 2021 - Elsevier
The memory-based diffusion systems have wide applications in practice. Hopf bifurcations
are observed from such systems. To meet the demand for computing the normal forms of the …

[HTML][HTML] Spatio-temporal dynamics near the steady state of a planktonic system

T Zhang, X Liu, X Meng, T Zhang - Computers & Mathematics with …, 2018 - Elsevier
The study of spatio-temporal behaviour of ecological systems is fundamentally important as
it can provide deep understanding of species interaction and predict the effects of …

Dynamics analysis and numerical simulations of a stochastic non-autonomous predator–prey system with impulsive effects

S Zhang, X Meng, T Feng, T Zhang - Nonlinear Analysis: Hybrid Systems, 2017 - Elsevier
In this paper, we propose a stochastic non-autonomous Lotka–Volterra predator–prey
model with impulsive effects and investigate its stochastic dynamics. We first prove that the …

[PDF][PDF] Global dynamics analysis of a nonlinear impulsive stochastic chemostat system in a polluted environment

X Meng, L Wang, T Zhang - J. Appl. Anal. Comput, 2016 - jaac-online.com
This paper intends to develop a new method to obtain the threshold of an impulsive stochastic
chemostat model with saturated growth rate in a polluted environment. By using the theory …

Spatio-temporal dynamics of a reaction-diffusion system for a predator–prey model with hyperbolic mortality

T Zhang, Y Xing, H Zang, M Han - Nonlinear Dynamics, 2014 - Springer
We investigate the effects of diffusion on the spatial dynamics of a predator–prey model with
hyperbolic mortality in predator population. More precisely, we aim to study the formation of …

Overview of applications and developments in the harmony search algorithm

G Ingram, T Zhang - Music-Inspired Harmony Search Algorithm: Theory …, 2009 - Springer
The Harmony Search (HS) algorithm appeared around the year 2000 and it now has a
substantial literature. The aim of this chapter is to inform the reader of the diversity of HS …

Pattern dynamics of a diffusive toxin producing phytoplankton–zooplankton model with three-dimensional patch

D Jia, T Zhang, S Yuan - International Journal of Bifurcation and …, 2019 - World Scientific
In this paper, the Turing pattern formation in a diffusive toxin producing phytoplankton–zooplankton
model with three-dimensional patch is investigated. Firstly, the conditions for the …

[HTML][HTML] Dynamics of a novel nonlinear stochastic SIS epidemic model with double epidemic hypothesis

X Meng, S Zhao, T Feng, T Zhang - Journal of Mathematical Analysis and …, 2016 - Elsevier
In this paper, we propose new mathematical models with nonlinear incidence rate and double
epidemic hypothesis. Then we dedicate to develop a method to obtain the threshold of the …

Spatial dynamics in a predator-prey model with herd behavior

S Yuan, C Xu, T Zhang - Chaos: An Interdisciplinary Journal of …, 2013 - pubs.aip.org
In this paper, a spatial predator-prey model with herd behavior in prey population and quadratic
mortality in predator population is investigated. By the linear stability analysis, we obtain …
