What is it about?
One way of optimizing at the same time the body of the brain of modular robots is through a two-levels optimization scheme: in the inner loop, you let the brain learn how to control the body; in the outer, you search in the space of bodies through an evolutionary alforithm. This paper shows that the encoding for the body in the outer loop does impact on the learning ability, performed through reinforcement learning, of the inner loop.

Why is it important?
Understanding the interplay between different adaptation forms performed at different time scales (here, evolution of the body and learning of the brain) is a key step towards more autonomous robotic systems. In facts, adaptation at different time scale may enable robots to successfully face environmental changes without the intervention of human operators.
