             The representation of a learning or search problem can greatly impact its 
        performance. An alternative to hand-constructing an appropriate representation is to let

             the learning method adapt its own representation. We investigate this in a setup 
        where building blocks and assemblies thereof are coevolved. Building blocks may

             employ other building blocks, thus leading to hierarchical constructions. In 
        experiments, this is observed to lead to highly compact representations of sequences

             that are useful as building blocks. The method is able to solve problems requiring 
        long sequences of primitive operators. Control experiments using a conventional

        problems. Limitations of the current method are discussed. .
