Coevolution on tunable fitness landscapes
I examine the statistical properties of a NKC model of biological evolution in which species interact and compete to maximize their individual fitness. Species are modeled as adaptive walkers moving on deformable fitness landscapes. The nature of these landscapes is controlled by a small set of free parameters; by tuning them, I investigate the different phases of the model and search in partic...
متن کاملRed Queen Coevolution on Fitness Landscapes
Species do not merely evolve, they also coevolve with other organisms. Coevolution is a major force driving interacting species to continuously evolve exploring their fitness landscapes. Coevolution involves the coupling of species fitness landscapes, linking species genetic changes with their inter-specific ecological interactions. Here we first introduce the Red Queen hypothesis of evolution ...
متن کاملCo-evolution of Fitness Maximizers and Fitness Predictors
We introduce an estimation of distribution algorithm (EDA) based on co-evolution of fitness maximizers and fitness predictors for improving the performance of evolutionary search when evaluations are prohibitively expensive. Fitness predictors are lightweight objects which, given an evolving individual, heuristically approximate the true fitness. The predictors are trained by their ability to c...
متن کاملAnimal - Animat Coevolution : Using the Animal Population as Fitness Function *
We show an artificial world where animals (humans) and animats (software agents) interact in a coevolutionary arms race. The two species each use adaptation schemes of their own. Learning through interaction with humans has been out of reach for evolutionary learning techniques because too many iterations are necessary. Our work demonstrates that the Internet is a new environment where this may...
متن کاملPredictors of fitness to practise declarations in UK medical undergraduates.
BACKGROUND Misconduct during medical school predicts subsequent fitness to practise (FtP) events in doctors, but relatively little is known about which factors are associated with such issues during undergraduate education. This study exploits the newly created UK medical education database (UKMED), with the aim of identifying predictors of conduct or health-related issues that could potentiall...
