changedEvolution: MAP-Elites algorithm implemented to improve the speed and efficiency of evolutionary search
addedNew Neuron Type Available: "Leaky integrate-and-fire neurons" are now an option for brain neurons, allowing a more realistic brain type
addedNew CPG Type: "Gated motor gait prior" is now an option for central pattern generator (CPG), enabling strong global rhythmic movement
addedNew Plant Type: Poison Plants are now in the simulation; when eaten they decrease the energy of animats
addedNew Simulation Option: choose the number of food plants and poison plants in the simulation
addedNew Simulation Option: choose between 2 neuroevolution methods, NEAT or Deep-HyperNEAT
