iProver --- an instantiation-based theorem prover for first-order logic
iProver v2.7 (post CASC-26, 2017)
iProver is implemented in OCaml.
Features and supported input formats:
- First-order theorem proving: TPTP CNF/TFF/TCF/FOF (TFF/FOF with external clausifiers)
- Finite model finding: TPTP
- QBF: QDIMACS
- Hardware verification: AIGER
- First-order verification:
an extension of TPTP for specifying first-order transition systems and verification conditions
- Planning: PDDL (in progress )
Easy to install and use:
- install OCaml v4.04 or later
- iproveropt problem.p
Project leader: Konstantin Korovin (korovin[@]cs.man.ac.uk), the University of Manchester, UK.
- core, instantiaiton, resolution, finite model finding, preprocessing: Konstantin Korovin
- proofs/unsat cores: Christoph Sticksel
- bounded model checking, k-induction, AIG: Dmitry Tsarkov, Christoph Sticksel, KK
- abstraction refinement, Julio Cesar Lopez Hernandez, KK
- planning: Martin Suda, KK
