Influence of the variance of degree distributions on the evolution of cooperation in complex networks

Tsukamoto, Ei; Shirayama, Susumu - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 3, pp. 577-586

We study how initial network structure affects the evolution of cooperation in a spatial prisoner’s dilemma game. The … degree distribution, and inquire how it affects the evolution of cooperation by three methods of imitation. For every method …, it was found that a scale-free network does not always promote the evolution of cooperation, and that there exists an …

Effect of imitation in a competing and evolving population in different situations

Quan, Hongjun; Deng, Gang - In: Physica A: Statistical Mechanics and its Applications 377 (2007) 2, pp. 625-632

The effect of imitation in a competing and evolving population in different situations is studied. Agents in the population are repeatedly competing to be in a minority and they have a common strategy. Each agent has a parameter p characterizing the probability that he is following the...

Memory distribution in complex fitness landscapes

Diaz Ochoa, Juan G. - In: Physica A: Statistical Mechanics and its Applications 386 (2007) 2, pp. 752-755

In a co-evolutionary context, the survive probability of individual elements of a system depends on their relation with their neighbors. The natural selection process depends on the whole population, which is determined by local events between individuals. Particular characteristics assigned to...

Multiple choice minority game

Chow, F.K; Chau, H.F - In: Physica A: Statistical Mechanics and its Applications 319 (2003) C, pp. 601-615

Minority game is a model of heterogeneous players who think inductively. In this game, each player chooses one out of two alternatives every turn and those who end up in the minority side wins. It is instructive to extend the minority game by allowing players to choose one out of many...

Simulating the wealth distribution with a Richest-Following strategy on scale-free network

Hu, Mao-Bin; Jiang, Rui; Wu, Qing-Song; Wu, Yong-Hong - In: Physica A: Statistical Mechanics and its Applications 381 (2007) C, pp. 467-472

In this paper, we investigate the wealth distribution with agents playing evolutionary games on a scale-free social network adopting the Richest-Following strategy. Pareto's power-law distribution (1897) of wealth is demonstrated with power factor in agreement with that of US or Japan. Moreover,...

Quantitative agent-based firm dynamics simulation with parameters estimated by financial and transaction data analysis

Ikeda, Yuichi; Souma, Wataru; Aoyama, Hideaki; Iyetomi, … - In: Physica A: Statistical Mechanics and its Applications 375 (2007) 2, pp. 651-667

Firm dynamics on a transaction network is considered from the standpoint of econophysics, agent-based simulations, and game theory. In this model, interacting firms rationally invest in a production facility to maximize net present value. We estimate parameters used in the model through...

Rational behavior is a ‘double-edged sword’ when considering voluntary vaccination

Zhang, Haifeng; Fu, Feng; Zhang, Wenyao; Wang, Binghong - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 20, pp. 4807-4815

Of particular importance for public health is how to understand strategic vaccination behavior in social networks. Social learning is a central aspect of human behavior, and it thus shapes vaccination individuals’ decision-making. Here, we study two simple models to address the impact of the...

Quantum games

Figueiredo, J.M.A - In: Physica A: Statistical Mechanics and its Applications 335 (2004) 3, pp. 539-553

A new class of stochastic variables, governed by a specific set of rules, is introduced. These rules force them to loose some properties usually assumed for this kind of variables. We demonstrate that stochastic processes driven by these random sources must be described using a probability...

Stochastic short-term maintenance scheduling of GENCOs in an oligopolistic electricity market

Ghazvini, Fotouhi; Ali, Mohammad; Canizes, Bruno; Vale, Zita - In: Applied Energy 101 (2013) C, pp. 667-677

In the proposed model, the independent system operator (ISO) provides the opportunity for maintenance outage rescheduling of generating units before each short-term (ST) time interval. Long-term (LT) scheduling for 1 or 2years in advance is essential for the ISO and the generation companies...

An efficient and fair solution for communication graph games

van den Brink, René; Khmelnitskaya, Anna; van der … - In: Economics Letters 117 (2012) 3, pp. 786-789

We introduce an efficient solution for games with communication graph structures and show that it is characterized by efficiency, fairness and a new axiom called fair distribution of the surplus.
