Evolutionary dynamics on the complete graph

NOTE: due to the many links of a complete graph, the dynamical layout of the graph is likely taking some time. Depending on the speed of your computer some patience may be required.

Because mutants can spread to any part of the graph in a single step, the invasion process progresses quickly and does not exhibit any characteristic patterns.

For the simulations, the population size is \(N=100\) and hence \(4'950\) links. 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 only between \(10-15\) generations for the mutant to reach fixation.

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.

--fitness <r,m>: fitness of residents r and of mutants m.
