Global dynamics for a class of discrete fractional epidemic model with reaction-diffusion
Lu Zhenzhen, Yu Yongguang, Xu Weiyi +2
In recent years, discrete fractional epidemic models with reaction-diffusion have become increasingly popular in the literature, not only for its necessity of numerical simulation,…
Stability Analysis of Short Memory Fractional Differential Equations
Xudong Hai, Guojian Ren, Yongguang Yu +2
In this paper, a fractional derivative with short-term memory properties is defined, which can be viewed as an extension of Caputo fractional derivative. Then, some properties of t…
Distributed Second-order Multi-Agent Optimization over unbalanced network without boundedness of gradients
Lipo Mo, Haokun Hu, Yongguang Yu +1
This paper is mainly devoted to the distributed second-order multi-agent optimization problem with unbalanced and directed networks. To deal with this problem, a new distributed al…
Constrained H-infinity Consensus with Nonidentical Constraints
Lipo Mo, Yingmin Jia, Yongguang Yu
This note considers the constrained H-infinity consensus of multi-agent networks with nonidentical constraint sets. An improved distributed algorithm is adopted and a nonlinear con…
A fractional-order SEIHDR model for COVID-19 with inter-city networked coupling effects
Zhenzhen Lu, Yongguang Yu, YangQuan Chen +4
In this paper, a mathematical model is proposed to analyze the dynamic behavior of COVID-19. Based on inter-city networked coupling effects, a fractional-order SEIHDR system with t…
Forecast analysis of the epidemics trend of COVID-19 in the United States by a generalized fractional-order SEIR model
Conghui Xu, Yongguang Yu, QuanChen Yang +1
In this paper, a generalized fractional-order SEIR model is proposed, denoted by SEIQRP model, which has a basic guiding significance for the prediction of the possible outbreak of…
Optimal Randomness in Swarm-Based Search
Jiamin Wei, YangQuan Chen, Yongguang Yu +1
Lévy flights is a random walk where the step-lengths have a probability distribution that is heavy-tailed. It has been shown that Lévy flights can maximize the efficiency of resour…
Noise-synchronizability of opinion dynamics
Wei Su, Ge Chen, Yongguang Yu +1
With the analysis of noise-induced synchronization of opinion dynamics with bounded confidence (BC), a natural and fundamental question is what opinion structures can be synchroniz…
Noise-based control of opinion dynamics
Wei Su, Xianzhong Chen, Yongguang Yu +1
Designing feasible control strategies for opinion dynamics in complex social systems has never been an easy task. It requires a control protocol which 1) is not enforced on all ind…
Free Information Flow Benefits Truth Seeking
Wei Su, Yongguang Yu
How can we approach the truth in a society? It may depend on various factors. In this paper, using a well-established truth seeking model, we show that the persistent free informat…
Finite-Time Elimination of Disagreement of Opinion Dynamics via Covert Noise
Wei Su, Ge Chen, Yongguang Yu
Eliminating disagreement in a group is usually beneficial to the social stability. In this paper, using the well-known Hegselmann-Krause (HK) model, we design a quite simple strate…
Partial Convergence of Heterogeneous Hegselmann-Krause Opinion Dynamics
Wei Su, Yongguang Yu
In opinion dynamics, the convergence of the heterogeneous Hegselmann-Krause (HK) dynamics has always been an open problem for years which looks forward to any essential progress. I…
