Environments. Environmental signals (green) and nutrient abundance for five environments (bottom to top: AND, OR, A, B, XOR) shown as a function of time steps within one epoch. Nutrient presence is a delayed function of the two signals. One epoch is shown for each environment, which consists of 4,500 time units.
