Strategies for Resource Allocation of Two Competing Companies using Genetic Algorithm
Wing Keung Cheung, Kwok Yip Szeto
We investigate various strategic locations of shops in shopping malls in a metropolis with the aim of finding the best strategy for final dominance of market share by a company in…
Role of Zealots on the Adaptive Voter Model
Ka Wai Cheung, Chung Him Liu, Kwok Yip Szeto
The voter model has been extensive studied as an opinion dynamic model, and the role of the zealots has only been discussed recently. We introduce the adaptive voter model with zea…
First-passage time distribution for random walks on complex networks using inverse Laplace transform and mean-field approximation
Mucong Ding, Kwok Yip Szeto
We obtain an exact formula for the first-passage time probability distribution for random walks on complex networks using inverse Laplace transform. We write the formula as the sum…
Selection of Random Walkers that Optimizes the Global Mean First-Passage Time for Search in Complex Networks
Mucong Ding, Kwok Yip Szeto
We design a method to optimize the global mean first-passage time (GMFPT) of multiple random walkers searching in complex networks for a general target, without specifying the prop…
Field Induced Oscillation of Two Majorana Modes in a Quantum Ring
Yue Yu, Kwok Yip Szeto
We calculate the topological boundary modes found for quantum wire for a quantum ring. For the symmetric ring we find analytical solutions for two quasi-particles identifiable as t…
Analysis of Time Scale to Consensus in Voting Dynamics with more than Two Options
Degang Wu, K. Y. Szeto
We generalize a binary majority-vote model on adaptive networks to its plurality-vote counterpart and analyze the time scale to consensus when voters are given more than two option…
Field Induced Oscillation of Two Majorana Modes for a finite Quantum Wire
Yue Yu, Kwok Yip Szeto
The evolution of quantum walk on a finite wire under a small increment of vector potential can exhibit intrinsic quantum oscillation of the two topologically protected bound st…
Does Having More Options Mean Harder to Reach Consensus?
Degang Wu, Kwok Yip Szeto
We generalize a binary majority-vote model on adaptive networks to a plurality-vote counterpart. When opinions are uniformly distributed in the population of voters in the initial…
Winning in Sequential Parrondo Games by Players with Short-Term Memory
Ka Wai Cheung, Ho Fai Ma, Degang Wu +2
The original Parrondo game, denoted as AB3, contains two independent games: A and B. The winning or losing of A and B game is defined by the change of one unit of capital. Game A i…
Symmetry Protected Topological Phases and Majorana Mode in One-dimensional Quantum Walk with Boundary
Ho Tat Lam, Yue Yu, Kwok Yip Szeto
The topological phases in one-dimensional quantum walk can be classified by the coin parameters. By solving for the general exact solutions of bound states in one-dimensional quant…
Ramsauer effect in one-dimensional quantum walk with multiple defects
Ho Tat Lam, Kwok Yip Szeto
Experimental observations of quantum walks in one dimension have provided many exciting applications in quantum computing, while recent theoretical investigation of single phase de…
Optimization of Reliability of Network of Given Connectivity using Genetic Algorithm
Ho Tat Lam, Kwok Yip Szeto
Reliability is one of the important measures of how well the system meets its design objective, and mathematically is the probability that a system will perform satisfactorily for…
Extended Parrondo's Game and Brownian Ratchets: Strong and Weak Parrondo Effect
Degang Wu, Kwok Yip Szeto
Inspired by the flashing ratchet, Parrondo's game presents an apparently paradoxical situation. Parrondo's game consists of two individual games, game A and game B. Game A is a sli…
Comparing the reliability of networks by spectral analysis
Zitao Wang, Kwok Yip Szeto
We provide a method for the ranking of the reliability of two networks with the same connectance. Our method is based on the Cheeger constant linking the topological property of a…
Phase diagram of Symmetric Iterated Prisoner's Dilemma of Two-Companies with Partial Imitation Rule
Liangsheng Zhang, Wenjin Chen, Mathis Antony +1
The problem of two companies of agents with one-step memory playing game is investigated in the context of the Iterated Prisoner's Dilemma under the partial imitation rule, where a…
Imitation with incomplete information in 2x2 games
Mathis Antony, Degang Wu, K Y Szeto
Evolutionary game theory has been an important tool for describing economic and social behaviour for decades. Approximate mean value equations describing the time evolution of stra…
Connecting boundary and interior - "Gauss's law" for graphs
Ching King Chan, Kwok Yip Szeto
The Gauss's law, in an abstract sense, is a theorem that relates quantities on the boundary (flux) to the interior (charge) of a surface. An identity for soap froths were proved wi…
Detection of network inhomogeneity by total neighbor degree
H. W. Lau, K. Y. Szeto
Inhomogeneity in networks can be detected by the analysis of the correlation of the total degree of nearest neighbors. This is illustrated by two models. The first one is a random…
Structure Profile by a Model of Precipitation
Zhenggang Wang, Kwok Yip Szeto
The organizational structure of a network is investigated with a simulated precipitation model which does not make use of prior knowledge about the community structure of the netwo…
Asymptotic analysis of first passage time in complex networks
Hon Wai Lau, Kwok Yip Szeto
The first passage time (FPT) distribution for random walk in complex networks is calculated through an asymptotic analysis. For network with size and short relaxation time $τ\l…
Topological correlations in soap froths
