| N |
Maximal number of individuals in the system |
| K |
Number of cells in the neighborhood, defined by the cooperation and reproduction radii that are assumed to be equal |
| m |
Number of loci that need to be mutated to achieve the complex phenotype |
| R |
Reproduction probability of the wild-type |
| R+
|
Reproduction probability of the complex phenotype or when all products are provided as shared goods. |
| R−
|
Probability of intermediate mutants in the absence of shared goods. |
| D |
Death probability for individuals. |
| f |
Cooperation cost, subtracted from the reproduction probability for each cooperating locus. |
