abstract = "A novel Artificial Life paradigm is proposed where
autonomous agents are controlled via genetically
encoded Evolvable Mathematical Models (EMMs).
Agent/environment inputs are mapped to agent outputs
via equation trees which are evolved using Genetic
Programming. Equations use only the four basic
mathematical operators: addition, subtraction,
multiplication and division. Experiments on the
discrete Double-T Maze with Homing problem are
performed; the source code has been made available.
Results demonstrate that autonomous controllers with
learning capabilities can be evolved as analytical
mathematical models of behaviour, and that
neuroplasticity and neuromodulation can emerge within
this paradigm without having these special
functionalities specified a priori.",
