Abstract

This paper describes a formulation of reinforcement learning thatenables learning in noisy, dynamic environments such as in thecomplex concurrent multi-robot learning domain. The methodologyinvolves minimizing the learning space through the use of behaviors andconditions, and dealing with the credit assignment problem throughshaped reinforcement in the form of heterogeneous reinforcementfunctions and progress estimators. We experimentally validate theapproach on a group of four mobile robots learning a foraging task.
