How it works

Every fly runs a live copy of a slice of the real fruit-fly connectome: 6,484 neurons and 193,169 connections taken from the FlyEM male-CNS wiring diagram, through the open Lulzx/fly-brain project.

The wiring does not say how strong synapses are or when to act. Those 8 numbers per fly are evolved: when a fly dies, the next one hatches from the best brains so far, slightly mutated.

Where to go (the path) is supplied by the game, as in other embodied fly simulators. The brain decides whether to flee, push on, or eat.
