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.

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.
- --resident <r>
- fitness of resident r.
- --mutant <m>
- fitness of mutant m.
- --initfreqs <m:r>
- initial frequencies of residents r and mutants m. Frequencies that do not add up to 100% are scaled accordingly. If either frequency is zero, the population is initialized to a homogenous state with just a single, randomly placed individual of the opposite type.
