GitHub - bdeli/Proof-Logic-Checker: Propositional Logic checker

WebThe kinds of inference rules and decision procedures that one writes for proofs involving equality and rewriting are rather different from proofs that one might write in first-order logic using, say, sequent calculus or natural deduction. For example, equational logic proofs are often chains of replacements or applications of oriented rewriting and normal forms. In … WebNov 29, 2014 · 5. Short answer: No. Medium Answer: Can't really be done, though one could write a program to check the validity of a given proof fairly easily. In the case of propositional logic, the problem of automatically finding a proof is NP-complete (though it is decidable!), and in first order logic there are true theorems for which the prover would ... box and arrow model speech https://oscargubelman.com

Isabelle is a generic theorem prover with a fragment of higher-order logic as a metalogic for defining object logics. Isabelle also provides proof terms. We formalize this metalogic and the language of proof terms in Isabelle/HOL, define an executable (but inefficient) proof term checker and prove its correctness w.r.t. the …
