Strategy constrained by cognitive limits, and the rationality of belief-revision policies
Sperry-Taylor, Ashton T. - In: Games 8 (2017) 1, pp. 1-13
Strategy is formally defined as a complete plan of action for every contingency in a game. Ideal agents can evaluate every contingency. But real people cannot do so, and require a belief-revision policy to guide their choices in unforeseen contingencies. The objects of belief-revision policies...

On rational choice and the representation of decision problems
Oliva, Paulo; Zahn, Philipp - In: Games 12 (2021) 4, pp. 1-21
In economic theory, an agent chooses from available alternatives-modeled as a set. In decisions in the field or in the lab, however, agents do not have access to the set of alternatives at once. Instead, alternatives are represented by the outside world in a structured way. Online search results...

Evolution of groupwise cooperation : generosity, paradoxical behavior, and non-linear payoff functions
Kurokawa, Shun; Wakano, Joe Yuichiro; Ihara, Yasuo - In: Games 9 (2018) 4/100, pp. 1-24
Evolution of cooperation by reciprocity has been studied using two-player and n-player repeated prisoner’s dilemma games. An interesting feature specific to the n-player case is that players can vary in generosity, or how many defections they tolerate in a given round of a repeated game....

When and how does mutation-generated variation promote the evolution of cooperation?
Spichtig, Mathias; Egas, Martijn - In: Games 10 (2019) 1/4, pp. 1-17
Mutation-generated variation in behavior is thought to promote the evolution of cooperation. Here, we study this by distinguishing two effects of mutation in evolutionary games of the finitely repeated Prisoner’s Dilemma in infinite asexual populations. First, we show how cooperation can...

Modeling poker challenges by evolutionary game theory
Javarone, Marco Alberto - In: Games 7 (2016) 4, pp. 1-17
We introduce a model for studying the evolutionary dynamics of Poker. Notably, despite its wide diffusion and the raised scientific interest around it, Poker still represents an open challenge. Recent attempts for uncovering its real nature, based on statistical physics, showed that Poker in...

Evolutionary game between commensal and pathogenic microbes in intestinal microbiota
Wu, Amy; Ross, David - In: Games 7 (2016) 3, pp. 1-7
The human intestinal microbiota plays a fundamental role in host health and is associated with many diseases when the homeostasis is disturbed. Although recent achievements in metagenomic sequencing have begun to reveal the variety of microbial composition associated with healthy and disease...

Evolution of cooperation for multiple mutant configurations on all regular graphs with n ≤ 14 players
Richter, Hendrik - In: Games 11 (2020) 1/12, pp. 1-18
We study the emergence of cooperation in structured populations with any arrangement of cooperators and defectors on the evolutionary graph. In a computational approach using structure coefficients defined for configurations describing such arrangements of any number of mutants, we provide...

Cultural transmission and extortion
Ridinger, Garret - In: Games 9 (2018) 3/49, pp. 1-10
This paper explores the role of cultural transmission in extortion. Extortion is modeled as an asymmetric contest where individuals from one group attempt to take from individuals in another group. Using a model of cultural transmission, this paper finds the existence of a unique asymptotically...

Evolution of decisions in population games with sequentially searching individuals
Priklopil, Tadeas; Chatterjee, Krishnendu - In: Games 6 (2015) 4, pp. 413-437
In many social situations, individuals endeavor to find the single best possible partner, but are constrained to evaluate the candidates in sequence. Examples include the search for mates, economic partnerships, or any other long-term ties where the choice to interact involves two parties....
