Ferrari, Fiorentini and Fiorino made fCube i.e. \(F^{3}\).

1. FCube Prover Online

  • FCube prover online is version 4.1 of FCube-verbose, which provides proofs for intuitionistically valid formulas, and countermodels for those that are intuitionistically unprovable.
  • I only changed the code to use infix notation.
  • Mutatis mutandis, the php script is Carlo Capelli’s, on which runs Boole-Quine prover.
  • For the description of FCube algorithm, see [1] below.
