Should be quite easy, just add special casing/direct return for BooleanLiteralFormula at the start of https://github.com/moves-rwth/storm/blob/f37f477bc9995b9fa566dda20dd954e293497944/src/storm/logic/ExtractMaximalStateFormulasVisitor.cpp#L180
In PRISM, we have some additional logic that looks at the actual satisfying state sets for the maximal state subformulas and convert to true/false if the set covers all states of the model or is empty, respectively. In Storm, this info is not as easily available at that point of conversion...
When checking LTL formulas like
G (true U a)
, thetrue
is somehow replaced by a fresh atomic proposition before feeding it into spot. This potentially yields unnecessarily large automata.Obviously, this should be avoided.
