Evolutionary dynamics, intrinsic noise and cycles of co-operation
Alex J. Bladon, Tobias Galla, Alan J. McKane
We use analytical techniques based on an expansion in the inverse system size to study the stochastic evolutionary dynamics of finite populations of players interacting in a repeat…
Spherical grand-canonical minority games with and without score discounting
Alex Bladon, Thomas Richardson, Tobias Galla
We present a spherical version of the grand-canonical minority game (GCMG), and solve its dynamics in the stationary state. The model displays several types of transitions between…
