Coevolution of social norms and cooperation in public and private situations
Daiki Miyagawa, Koki Miyabara, Genki Ichinose
Cooperation in human society is sustained by reputation. In general, the reputation of an individual is determined by others who observe his behavior, but this rarely happens in pr…
Adapting paths against zero-determinant strategies in repeated prisoner's dilemma games
Daiki Miyagawa, Azumi Mamiya, Genki Ichinose
Long-term cooperation, competition, or exploitation among individuals can be modeled through repeated games. In repeated games, Press and Dyson discovered zero-determinant (ZD) str…
Conditions for the existence of zero-determinant strategies under observation errors in repeated games
Azumi Mamiya, Daiki Miyagawa, Genki Ichinose
Repeated games are useful models to analyze long term interactions of living species and complex social phenomena. Zero-determinant (ZD) strategies in repeated games discovered by…
How Lévy flights triggered by presence of defectors affect evolution of cooperation in spatial games
Genki Ichinose, Daiki Miyagawa, Erika Chiba +1
Cooperation among individuals has been key to sustaining societies. However, natural selection favors defection over cooperation. Cooperation can be favored when the mobility of in…
Winning by hiding behind others: An analysis of speed skating data
Genki Ichinose, Daiki Miyagawa, Junji Ito +1
In some athletic races, such as cycling and types of speed skating races, athletes have to complete a relatively long distance at a high speed in the presence of direct opponents.…
Robustness of football passing networks against continuous node and link removals
Genki Ichinose, Tomohiro Tsuchiya, Shunsuke Watanabe
We can construct passing networks when we regard a player as a node and a pass as a link in football games. Thus, we can analyze the networks by using tools developed in network sc…
Cellular automaton model with turning behavior in crowd evacuation
Daiki Miyagawa, Genki Ichinose
Effective evacuation policies in emergency situations are important to save lives. To develop such policies, simulation models based on cellular automata have been used for crowd e…
Strategies that enforce linear payoff relationships under observation errors in Repeated Prisoner's Dilemma game
Azumi Mamiya, Genki Ichinose
The theory of repeated games analyzes the long-term relationship of interacting players and mathematically reveals the condition of how cooperation is achieved, which is not achiev…
Reduced mobility of infected agents suppresses but lengthens disease in biased random walk
Genki Ichinose, Yoshiki Satotani, Hiroki Sayama +1
Various theoretical models have been proposed to understand the basic nature of epidemics. Recent studies focus on the effects of mobility to epidemic process. However, uncorrelate…
Network flow of mobile agents enhances the evolution of cooperation
Genki Ichinose, Yoshiki Satotani, Takashi Nagatani
We study the effect of contingent movement on the persistence of cooperation on complex networks with empty nodes. Each agent plays Prisoner's Dilemma game with its neighbors and t…
How mutation alters the evolutionary dynamics of cooperation on networks
Genki Ichinose, Yoshiki Satotani, Hiroki Sayama
Cooperation is ubiquitous at every level of living organisms. It is known that spatial (network) structure is a viable mechanism for cooperation to evolve. A recently proposed nume…
Evolution of Human-like Social Grooming Strategies regarding Richness and Group Size
Masanori Takano, Genki Ichinose
Human beings tend to cooperate with close friends, therefore they have to construct strong social relationships to recieve cooperation from others. Therefore they should have acqui…
Zero-determinant strategies in finitely repeated games
Genki Ichinose, Naoki Masuda
Direct reciprocity is a mechanism for sustaining mutual cooperation in repeated social dilemma games, where a player would keep cooperation to avoid being retaliated by a co-player…
How mutation alters fitness of cooperation in networked evolutionary games
Genki Ichinose, Yoshiki Satotani, Hiroki Sayama
Cooperation is ubiquitous in every level of living organisms. It is known that spatial (network) structure is a viable mechanism for cooperation to evolve. Until recently, it has b…
Positive and negative effects of social impact on evolutionary vaccination game in networks
Genki Ichinose, Takehiro Kurisaku
Preventing infectious disease like flu from spreading to large communities is one of the most important issues for humans. One effective strategy is voluntary vaccination, however,…
Transitions between homophilic and heterophilic modes of cooperation
Genki Ichinose, Masaya Saito, Hiroki Sayama +1
Cooperation is ubiquitous in biological and social systems. Previous studies revealed that a preference toward similar appearance promotes cooperation, a phenomenon called tag-medi…
Invasion of cooperation in scale-free networks: Accumulated vs. average payoffs
Genki Ichinose, Hiroki Sayama
It is well known that cooperation cannot be an evolutionary stable strategy for a non-iterative game in a well-mixed population. In contrast, structured populations favor cooperati…
Evolution of Fairness in the Not Quite Ultimatum Game
Genki Ichinose, Hiroki Sayama
The Ultimatum Game (UG) is an economic game where two players (proposer and responder) decide how to split a certain amount of money. While traditional economic theories based on r…
Robustness of cooperation on scale-free networks under continuous topological change
Genki Ichinose, Yuto Tenguishi, Toshihiro Tanizawa
In this paper, we numerically investigate the robustness of cooperation clusters in prisoner's dilemma played on scale-free networks, where the network topologies change by continu…
Adaptive long-range migration promotes cooperation under tempting conditions
Genki Ichinose, Masaya Saito, Hiroki Sayama +1
Migration is a fundamental trait in humans and animals. Recent studies investigated the effect of migration on the evolution of cooperation, showing that contingent migration favor…
