In biology, game theory is a branch of evolutionary theory that is particularly suited to the
study of interactions between individuals. The evolution of animal fighting behaviour was …

The evolutionary form of the iterated prisoner's dilemma (IPD) is a repeated game where
players strategically choose whether to cooperate with or exploit opponents and reproduce …

The concept of an evolutionary stable strategy (ESS) is a useful tool for studying the
dynamics of natural selection. One of its limitations, however, is that it does not capture the …

Every behaviourally responsive animal (including us) make decisions. These can be simple
behavioural decisions such as where to feed, what to feed, how long to feed, decisions …

The 50-year old concept of an evolutionarily stable strategy provided a key tool for theorists
to model ultimate drivers of behaviour in social interactions. For decades, economists …

We present models of adaptive change in continuous traits for the following situations:(1)
adaptation of a single trait within a single population in which the fitness of a given individual …

Equilibrium analysis in autonomous evolutionary models is of central importance for
developing long term treatments. This task typically includes checks on the existence and …

A strategy in a population game is evolutionarily stable if, when adopted by large enough a
majority in the population, it becomes advantageous against any mutant strategy. It is said to …

The concept of an evolutionarily stable strategy (ESS) in its original definition is
inappropriate for application to models where the pay-offs to the strategies depend on the …

In this paper we show that there are certain limits as to what applications of Maynard Smith's
concept of evolutionarily stable strategy (ESS) can tell us about evolutionary processes. We …
