On the Complexity of Elementary Modal Logics
Abstract
Modal logics are widely used in computer science. The complexity
of modal satisfiability problems has been investigated since the
1970s, usually proving results on a case-by-case basis. We prove a
very general classification for a wide class of relevant logics:
Many important subclasses of modal logics can be obtained by
restricting the allowed models with first-order Horn formulas. We
show that the satisfiability problem for each of these logics is
either NP-complete or PSPACE-hard, and exhibit a simple
classification criterion. Further, we prove matching PSPACE upper
bounds for many of the PSPACE-hard logics.
