Eigenvalue Based Approach for Global Consensus in Multiagent Systems with Nonlinear Dynamics
Published 2014-01-01“…By employing a Lyapunov function and graph theory, a sufficient condition is presented for the global exponential consensus of the multiagent system. The analytical result shows that, for a weakly connected communication graph, the algebraic connectivity of a redefined symmetric matrix associated with the directed graph is used to evaluate the global consensus of the multiagent system with nonlinear dynamics under the common linear consensus protocol. …”

A series transformation formula and related polynomials
Published 2005-01-01“…In one particular case, our formula reduces to a series transformation formula which appears in the works of Ramanujan and is related to the exponential (or Bell) polynomials. Another particular case, based on the geometric series, gives rise to a new class of polynomials called geometric polynomials.…”

Preliminary study on the connotation of flexibility in dynamically reconfigurable networks
Published 2012-08-01“…,the dynamic data channel varying with service demands,of reconfigurable networks was first exhibited and explained.Four dominant implications of the flexibility were then revealed as gradually mapping to demands,keeping global performance good,implicit isolation,and self-driven control.Finally,related quantitative models and methods for both determining the stable deviation of outcomes from demands and computing the volume of resource dynamically reconfigured were investigated by using the exponentially moving average,the n:m voting scheme,Markov decision processes (MDP) and reinforcement learning,respectively.…”

Structural properties and static robustness of Linux software network
Published 2019-11-01“…The source code of the Linux software was analyzed,and the directed function call network model,the weak coupling network model of software system,the strong coupling network model and the strong connected subgraph model were built.The characteristics and static robustness of the four networks were studied.The results show that four networks all show ‘small-world’ property.The out-degree distribution of the six modules in the Linux network generally follows the exponential distribution,and the in-degree distribution of the six modules follows the power law.The best attacking strategy was distinct when different robustness evaluation indicator was adopted.For the weak connectivity indicator,high in-degree attacking strategy was of the greatest damage to the weakly coupled software network.…”

DNA algorithm of primeness test based on finite automaton
Published 2006-01-01“…Finite automaton,a computational model of extremely limited computing ability,was proved to have the capa-bility of solving primeness test by construction.Then,a DNA algorithm of the primeness test based on finite automaton was proposed.Furthermore,the method of constructing the finite automaton was presented in detail.The state of the fi-nite automaton was encoded by single-stranded DNA.The input was encoded by double-stranded DNA.The transition rule was represented by a double strand with a ring.The state of transition was realized by enzyme-mediated chemical reactions.The innovation of the algorithm is that it can be applied not only in primeness test but also in prime factoriza-tion and further in attack of RSA cipher.The advantage of this method is that it can be easily implemented.The time re-quired is polynomial in the size of the problem instead of exponential in the size of the problem.…”
