Dietl and Kelley—predator-prey Arms Races
Arms races between predators and prey may be driven by two related processes—escalation and coevolution. Escalation is enemy-driven evolution. In this top-down view of an arms race, the role of prey (with the exception of dangerous prey) is downplayed. In coevolution, two or more species change reciprocally in response to one another; prey are thought to drive the evolution of their predator, a...
متن کاملCoevolving Predator and Prey Robots: Do "Arms Races" Arise in Artificial Evolution?
Coevolution (i.e., the evolution of two or more competing populations with coupled fitness) has several features that may potentially enhance the power of adaptation of artificial evolution. In particular, as discussed by Dawkins and Krebs [3], competing populations may reciprocally drive one another to increasing levels of complexity by producing an evolutionary "arms race." In this article we...
متن کاملArms Races and Car Races
Evolutionary car racing (ECR) is extended to the case of two cars racing on the same track. A sensor representation is devised, and various methods of evolving car controllers for competitive racing are explored. ECR can be combined with co-evolution in a wide variety of ways, and one aspect which is explored here is the relative-absolute fitness continuum. Systematical behavioural differences ...
متن کاملEvolution: Sexual Arms Races
The reproductive interests of males and females usually differ, resulting in sexual conflict. Recent studies in which experimental selection trials were carried out under conditions of either 'high' or 'low' sexual conflict show that conflict can promote speciation and reduce female reproductive success.
متن کاملArms Races and Negotiations
Two players simultaneously decide whether or not to acquire new weapons in an arms race game. Each player’s type determines his propensity to arm. Types are private information, and are independently drawn from a continuous distribution. With probability close to one, the best outcome for each player is for neither to acquire new weapons (although each prefers to acquire new weapons if he think...
