Points are also accumulated for successfully picking up an item of food. Subsequently, points are accumulated for walking back toward the nest while carrying food, and finally, points are accumulated for dropping food directly on the nest. An evolved neural network Neurons are drawn as dots around the perimeter and synapses are the lines connecting the dots. Blue neurons receive input only from the labeled senses, not synapses. Yellow neurons send output only to motors, not synapes.
Black neurons are available for hidden layers in the neural network.
Green synapses are excitatory with a strength proportional to the greeness and red synapses are inhibitory in similar fashion. I consider this project to be a partial success. However, the foraging is not perfect. Even after 7000 generations, the colonies still have biases in their behavior. They might only forage on the north side off the nest leaving half the map mostly untouched for example.
