** Enumeration Classes Defined by Circuits **

We refine the complexity landscape for enumeration problems by introducing very low classes defined by using Boolean circuits as enumerators. We locate well-known enumeration problems, e.g., from graph theory, Gray code enumeration, and propositional satisfiability in our classes. In this way we obtain a framework to distinguish between the complexity of different problems known to be computable with polynomial delay, for which a formal way of comparison was not possible to this day. The approach offers a different measure of efficient enumeration such as the one defined using Constant Delay in the context of enumeration for query answering.
This is joint work with Nadia Creignou and Heribert Vollmer.
