Fuzzy Classifier Systems (FCS) implement a mapping fr om real numbers to real numbers, through fuzzy interpretation of input and output. Reinforcement Learning (RL) algorithms can be succesfully applied to develop learning FCS analogously to what can be done with Learning Classifier Systems (LCS). We motivate this approach and we present; a methodology to extend straightforwardly reinforcement distribution algorithms originally designed for crisp input. and output to fully exploit the features of FCS.
