Symbolic WS1S

8 pagesPublished: December 18, 2015

Abstract

We extend weak monadic second-order logic of one successor (WS1S) to symbolic alphabets by
allowing character predicates to range over decidable first order theories and not just finite alphabets.
We call this extension symbolic WS1S (s-WS1S). We then propose two decision procedures for such a
logic: 1) we use symbolic automata to extend the classic reduction from WS1S to finite automata to
our symbolic logic setting; 2) we show that every s-WS1S formula can be reduced to a WS1S formula
that preserves satisfiability, at the price of an exponential blow-up.

Keyphrases: mso, smt, symbolic automata
