Evolutionary convergence
League dreams of breeding players with titanium knees, they will have to make do with bones and ligaments for the foreseeable future. Constraints come in many forms, from those that limit the range of variation available for natural selection to act upon (elephants with titanium legs seem unlikely to appear) to the physical forces of fluid dynamics, gravity and the like. In 1995, Kurt Schwenk u...
متن کاملConvergence of Nonautonomous Evolutionary Algorithm
We present a general criterion guaranteeing the stochastic convergence of a wide class of nonautonomous evolutionary algorithms used for finding the global minimum of a continuous function. This paper is an extension of paper [6], where autonomous case was presented. Our main tool here is a cocycle system defined on the space of probabilistic measures and its stability properties.
متن کاملContinuous Stability and Evolutionary Convergence
A stochastic process of long-term evolution due to mutation and selection is defined over an asexually reproducing population, with selection according to a population game with a one-dimensional continuity of pure strategies. Limiting the analysis to mutations of small effect, it is shown that long-term dynamic stability in such a process is equivalent to continuous stability in the relevant p...
متن کاملEvolutionary convergence and biologically embodied cognition.
The study of evolutionary patterns of cognitive convergence would be greatly helped by a clear demarcation of cognition. Cognition is often used as an equivalent of mind, making it difficult to pin down empirically or to apply it confidently beyond the human condition. Recent developments in embodied cognition and philosophy of biology now suggest an interpretation that dissociates cognition fr...
متن کاملFast convergence in evolutionary equilibrium selection
Stochastic best response models provide sharp predictions about equilibrium selection when the noise level is arbitrarily small. The difficulty is that, when the noise is extremely small, it can take an extremely long time for a large population to reach the stochastically stable equilibrium. An important exception arises when players interact locally in small close-knit groups; in this case co...
