Dolmen provides a library and a binary to parse, typecheck, and evaluate languages used in automated deduction
Testing and benchmarking tool for logic-related programs.
Haskell interface to automated theorem provers
Efficient and multi-language generation from context free or sensitive grammars (CFG/CSG)
Parser and pretty printer for the TPTP language
A parser for the TPTP logic languages for automated theorem proving written in Scala
A verification conditions generator for Boogie programs
Library for TPTP-related utility services
A reasoner for Input/Output logic
Extract TPTP problems from a TSTP trace and reconstruct the proof in lambdapi (λΠ-calculus modulo theory).
Sort-Stratified Semantics for Temporal Conflict Detection between pairs of ODRL policies
Example axiom and problem files within the TPTP Format
TPTP problems and TSTP solutions of problems in classical propositional logic.
A formal, axiomatic treatment of libertarian property theory for Leo-III
Kernel-checked finite counter-models for Lean 4: Vampire finds a world where the axioms hold and a claim fails, and Lean's kernel certifies it. Proves what does NOT follow. Reproduced Nakamura's hand-built Spinoza counter-models automatically (2 elements vs 4 and 3), certified 185 TPTP problems, and scaled to a million facts.
TPTP problem file pre-processor for augmenting reasoning problems with extra axioms
