We show that feature logic extended by functional uncertainty is decidable, even if one admits cyclic descriptions. We present an algorithm, which solves feature descriptions containing functional un- certainty in two phases, both phases using a set of de- terministic and non-deterministic rewrite rules. We then compare our algorithm with the one of Kaplan and Maxwell, that does not cover cyclic feature de- scriptions.
