Abstract

In this paper, symmetry-based choice mechanisms are exploited to compute deterministic queries. We investigate a particular form of these choice mechanisms, called specified symmetry choice. This mechanism is efficient (i.e. computable in polynomial time) and can be added to Fixpoint Logic to give a language that is more powerful than the extension of Fixpoint with Counting.
