Evolutionary games under incompetence
The adaptation process of a species to a new environment is a significant area of study in biology. As part of natural selection, adaptation is a mutation process which improves survival skills and reproductive functions of species. Here, we investigate this process by combining the idea of incompetence with evolutionary game theory. In the sense of evolution, incompetence and training can be i...
متن کاملEvolutionary games on networks and payoff invariance under replicator dynamics
The commonly used accumulated payoff scheme is not invariant with respect to shifts of payoff values when applied locally in degree-inhomogeneous population structures. We propose a suitably modified payoff scheme and we show both formally and by numerical simulation, that it leaves the replicator dynamics invariant with respect to affine transformations of the game payoff matrix. We then show ...
متن کاملFixation times in evolutionary games under weak selection
In evolutionary game dynamics, reproductive success increases with the performance in an evolutionary game. If strategy A performs better than strategy B, strategy A will spread in the population. Under stochastic dynamics, a single mutant will sooner or later take over the entire population or go extinct. We analyze the mean exit times (or average fixation times) associated with this process. ...
متن کاملEvolutionary Games on Structured Populations under Weak Selection
All biological systems are, at some level, guided by the laws of natural selection and evolutionary dynamics. Adaptations with increased fitness tend to proliferate and fixate within populations. Those situations in which an individual’s fitness depends not only upon a static environment, but upon the fluctuating phenotypes of the surrounding population, fall within the domain of evolutionary g...
متن کاملFixation in Evolutionary Games under Non-Vanishing Selection
One of the most striking effect of fluctuations in evolutionary game theory is the possibility for mutants to fixate (take over) an entire population. Here, we generalize a recent WKB-based theory to study fixation in evolutionary games under non-vanishing selection, and investigate the relation between selection intensity w and demographic (random) fluctuations. This allows the accurate treatm...
