initialization | constraints during simulations | description | |
---|---|---|---|
parameters | |||
Std-Dev-environment-change | (0.04–1) | initialization value | determines the degree of environmental stochasticity environmentt + 1 = environmentt + N ∼ (0, Std-Dev-environment-change) |
plasticity-costs | (0–1) | initialization value | determines whether plasticity carries a load reducing odds of survival and reproducing |
mean-mutational-change | (0–0.002) | initialization value | determines both the probability of occurrence of genetic changes and their effect size on the phenotype |
emergent values | |||
environment | 0.5 | [0,1] | expresses the environmental conditions on a single dimension, the same one used to describe the phenotype, the genotype and the plasticity-range |
non-plastics and plastics | |||
phenotype | 0 | — | phenotypic value expressed in the same dimension as the environment |
genotype | 0 | — | in the absence of plasticity, the phenotype = genotype |
match | n.a. | — | absolute difference between the phenotypic value and the environmental value; the phenotype is optimized if match = 1 1 - |environment - phenotype| |
plastics only | |||
plasticity-range | 0 | — | the maximum phenotypic adjustment that a genotype is capable to increase match |
used-plasticity | n.a. | 0 ≤ used-plasticity ≤ plasticity-range | amount of the plasticity-range that is actually used by an individual during development |
