Description
Evolutionary game theory provides a powerful and flexible tool to the investigation of the evolution of interacting individuals. In this study we focus on the evolution of “staying together” groups, in which new individuals in a population emerge only by splitting the previous group. These groups deserve a special attention, since many multicellular organisms use this mode of the organism development. Interactions between players in a group, provided by a two- player matrix game, affects both the group growth time as a whole and the probabilities of each player type to reproduce. In our model, we mainly focus on the population of containing two phenotypes either A or B and quantise the interactions between cells. The combination of the game played within the group and the fragmentation mode of producing new groups determine the population growth rate. Thus, the mode of fragmentation providing the largest growth rate λ is considered to be evolutionary optimal reproductive strategy.
