Environmental resilience via morphological diversity within machines
Alice Hein, Josh Bongard
Organisms contain diverse, sensorimotor parts across size scales and rapidly adapt to new environments, while machines contain only inert materials at smaller scales and struggle w…

Selection for short-term empowerment accelerates the evolution of homeostatic neural cellular automata
Caitlin Grasso, Josh Bongard
Empowerment -- a domain independent, information-theoretic metric -- has previously been shown to assist in the evolutionary search for neural cellular automata (NCA) capable of ho…

Empowered Neural Cellular Automata
Caitlin Grasso, Josh Bongard
Information-theoretic fitness functions are becoming increasingly popular to produce generally useful, task-independent behaviors. One such universal function, dubbed empowerment,…
