Abstract:       This paper focusses on reactive multi--agent systems in which
                (i) each agent only knows a specific part of the environment,
                (ii) each agent is specialized in a specific action, and
                (iii) actions of different agents can be incompatible. The 
                central problem addressed is how several agents can 
                collectively adapt to their environment by learning to
                generate a sequence of action sets that solves an environmental
                task. The contents and organization of the paper are as 
                follows. Section 1 briefly motivates the topic of action 
                selection and learning in multi--agent systems. Section 2 
                introduces a new algorithm called DFG (for ``Dissolution and 
                Formation of Groups'') for the reinforcement learning of 
                appropriate sequences of groups of concurrently active agents. 
                Section 3 provides theoretical and experimental results on
                the the DFG algorithm. Section 4 concludes with a brief 
                summary and an outlook on future work.
