SAT

Parametric SAT

In my diploma thesis I generalized successful algorithmic ideas for quantified satisfiability solving to the parametric case where there are parameters in the input problem. The output is then not necessarily a truth value but more generally a propositional formula in the parameters of the input. Since one can naturally embed propositional logic into first-order logic over Boolean algebras, the work amounts from a model-theoretic point of view to a quantifier elimination procedure for initial Boolean algebras.
