ABSTRACT The Iterated Prisoners Dilemma (IPD) has received much attention because of its ability to demonstrate altruistic behavior. How- ever, most studies focus on the synchronous case, where players make their decisions simultaneously. As this is implausible in most biological contexts, a more generalized approach is required to study the emergence of altruistic behavior in an evolutionary context. Here, we take previous results and present a generalized Markov model for asynchronous IPD, where both, one, or neither player can make a decision at a given time step. We show that the type of asynchronous timing introduced into the model influences the strategy that dominates. The framework presented here is a more biologically plausible scenario through which to investigate altruistic behavior.

    ABSTRACT: Cooperation in organisms, whether bacteria or primates, has been a difficulty for evolutionary theory since Darwin. On the assumption that interactions between pairs of individuals occur on a probabilistic basis, a model is developed based on the concept of an evolutionarily stable strategy in the context of the Prisoner's Dilemma game. Deductions from the model, and the results of a computer tournament show how cooperation based on reciprocity can get started in an asocial world, can thrive while interacting with a wide range of other strategies, and can resist invasion once fully established. Potential applications include specific aspects of territoriality, mating, and disease.

    ABSTRACT: Models of multi-agent systems usually update the states of all agents synchronously, but in many real life systems, agents behave asynchronously. Relatively little is yet known about the dynamic characteristics of asynchronous systems. Here we compare synchronous, random asynchronous, and ordered asynchronous updating schemes. Using one-dimensional (1D) cellular automata as a case study, we show that the type of update scheme strongly affects the dynamic characteristics of the system. We also show that global synchronisation can arise from local temporal coupling. Furthermore, it is possible to switch between chaotic, cyclic and modular behaviour by varying a single parameter, which suggests a possible mechanism by which environmental parameters influence emergent structure. We conclude that ordered asynchronous processes with local temporal coupling play a role in self-organisation within many multi-agent systems.

    ABSTRACT: There are many situations in which biological organisms cooperate despite obvious incentives to do otherwise. Such situations are commonly modelled by using a paradigm known as the prisoner's dilemma. In this way cooperative behaviour has previously been shown to emerge in a model population of strategies. If players can make probabilistic choices, taking into account their co-player's previous action, a strategy known as 'generous tit for tat' dominates the long-term behaviour of such a population. If they can also take into account their own previous action, a strategy of 'win stay, lose shift' dominates instead. These models assumed that participants make their decisions in synchrony, which seems improbable in many biological situations. Here we show that the timing of decisions is critical in determining which strategy emerges in the long run. If individuals make their decisions at different times, neither of the above strategies survives given the usual payoffs. In the former case, generous tit for tat succumbs to inveterate defectors, and in the latter a new strategy takes over. This 'firm but fair' strategy is retaliatory yet highly cooperative. In particular, continued exploitation of a sucker is no longer a successful behaviour.
