Onion structure and network robustness
Zhi-Xi Wu, Petter Holme
In a recent work [Proc. Natl. Acad. Sci. USA 108, 3838 (2011)], Schneider et al. proposed a new measure for network robustness and investigated optimal networks with respect to thi…
Modeling scientific-citation patterns and other triangle-rich acyclic networks
Zhi-Xi Wu, Petter Holme
We propose a model of the evolution of the networks of scientific citations. The model takes an out-degree distribution (distribution of number of citations) and two parameters as…
Diversity of reproduction time scale promotes cooperation in spatial prisoner's dilemma games
Zhi-Xi Wu, Zhihai Rong, Petter Holme
We study an evolutionary spatial prisoner's dilemma game where the fitness of the players is determined by both the payoffs from the current interaction and their history. We consi…
Effects of strategy-migration direction and noise in the evolutionary spatial prisoner's dilemma
Zhi-Xi Wu, Petter Holme
Spatial games are crucial for understanding patterns of cooperation in nature (and to some extent society). They are known to be more sensitive to local symmetries than e.g. spin m…
Effects of free will and massive opinion in majority rule model
Zhi-Xi Wu, Guanrong Chen
We study the effects of free will and massive opinion of multi-agents in a majority rule model wherein the competition of the two types of opinions is taken into account. To addres…
