Parametrised Complexity of Satisfiability in Temporal Logic

Abstract: We apply the concept of formula treewidth and pathwidth to computation tree logic, linear temporal logic, and the full branching time logic. Several representations of formulas as graphlike structures are discussed, and corresponding notions of treewidth and pathwidth are introduced. As an application for such structures, we present a classification in terms of parametrised complexity of the satisfiability problem, where we make use of Courcelle’s famous theorem for recognition of certain classes of structures… Show more

“…However, in this setting usually CNF-formulas are considered. Coping with this restriction, Lück et al [38] defined syntax circuits for temporal logic formulas that also allow arbitrary formulas. In our setting, we continue in this direction and define the syntax (or formula) structure with respect to a PDL-formula.…”

“…The technique of Courcelle's theorem [4] (see Prop. 6) has been used in different contexts: temporal logic [23], knowledge representation [13], and nonmonotonic logic [25]. Elberfeld et al [10] enriched Courcelle's theorem to also yield results for the complexity class XL.…”
