MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV ( that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Randomness, Heterogeneity and Population Dynamics

Jürgen Jost and Wei Li


We investigate the emergent population dynamics of an iterated game in which members of two antagonistic populations are randomly paired in each round. The basic setting is symmetric between these two populations, but this symmetry can be broken by giving the members of the two populations access to different strategy spaces or by assigning different values to parameters determining the composition or the evolution of the populations. In particular, we can investigate the effects of population diversity or stochasticity of the individual agents' actions, both for the competition between agents inside a population and for their benefits or disadvantages for the population as a whole.
