Evolutionary dynamics on the complete graph

On random regular graphs any vertex can be reached from any other one in relatively few steps. Consequentially, the invasion process of mutants is similar to the complete graph (or even unstructured populations) and no characteristic invasion patterns emerge, with the only difference that it takes a little longer.

For the simulations, the population size is \(N=1000\) and every vertex has \(k=3\) neighbours. The fitness of residents is set to \(1\) and that of mutants to \(2\). Thus, a single mutant has approximately a \(50\%\) chance to take over the population. Typically it takes around \(40\) generations for the mutant to reach fixation, which is around twice as long as in an unstructured population.

Game parameters

The list below describes only the few parameters related to the evolutionary dynamics of residents and mutants with fixed fitness (constant selection). Numerous other parameters are available to set population structures or update rules on the player as well as population level.
