Actually there are mechanical ways of generating Fitch style proofs. e. For the frequent case of propositional logic, the problem is decidable but co-NP-complete, and hence only exponential-time algorithms are believed to exist for general proof tasks. That's why throughout this video lesson, you'll learn how to construct direct style logic proofs to help make sense of the process and method. Using a direct proof, prove that the resulting argument is valid. a web application that decides statements in symbolic logic including modal logic, propositional logic and unary predicate logic (Disclaimer: In the worst case, the proof method may take just as many or more steps to find an answer as the truth table method.)
