Proof-search in natural deduction calculus for classical propositional logic

M Ferrari, C Fiorentini - Automated Reasoning with Analytic Tableaux and …, 2015 - Springer
We address the problem of proof-search in the natural deduction calculus for Classical
propositional logic. Our aim is to improve the usual naïve proof-search procedure where …

A forward unprovability calculus for intuitionistic propositional logic

C Fiorentini, M Ferrari - Automated Reasoning with Analytic Tableaux and …, 2017 - Springer
The inverse method is a saturation based theorem proving technique; it relies on a forward
proof-search strategy and can be applied to cut-free calculi enjoying the subformula …

An evaluation-driven decision procedure for G3i

M Ferrari, C Fiorentini, G Fiorino - ACM Transactions on Computational …, 2015 - dl.acm.org
It is well known that G3i, the sequent calculus for intuitionistic propositional logic where
weakening and contraction are absorbed into the rules, is not terminating. Indeed, due to the …

Duality between unprovability and provability in forward refutation-search for intuitionistic propositional logic

C Fiorentini, M Ferrari - ACM Transactions on Computational Logic …, 2020 - dl.acm.org
The inverse method is a saturation-based theorem-proving technique; it relies on a forward
