Example of an adaptation strategy produced by an optimized network. (A) Distribution of environmental cues $\xi$ represented by points in the environment space (color represents the actual environmental condition ${\epsilon }^{\mu }$). (B) Distribution of phenotypes produced by the optimized network, represented by points in the phenotype space. All points fall on a plane (gray shaded) spanned by the archetypes ${\psi }^{\mu }$. For these plots we used parameter values $\sigma =1$ for environmental noise and $\gamma =1$ for selection strength, which represent characteristic scales that are of the same order as the distance between two environments ${\epsilon }^{\mu }$ and between two archetypes ${\psi }^{\mu }$, respectively.
