Proving Theorems of Higher-Order Logic with SMT Solvers
Document: Official PDF Local PDF
Abstract:
Following the demand for increased proof automation in the interactive
theorem prover Isabelle, this thesis describes how satisfiability
modulo theories (SMT) solvers improve on the state of the art. SMT
solvers are automatic theorem provers with decision procedures for
several theories such as equality and linear arithmetic.
Our main contributions are a sound translation from Isabelle's
higher-order logic to the first-order logic of SMT solvers, and
efficient checking of proofs found by the solver Z3.
Based on a large evaluation, we find that many theorems can now be
proved automatically and almost instantaneously for which
time-consuming user ingenuity was previously required. Checking Z3's
proofs is fast thanks to our extensive optimizations.
Further contributions are a new tool and methodology to verify the
functional correctness of C code in conjunction with the automatic
program verifier VCC. We demonstrate their suitability on real-world
implementations of tree and graph algorithms.
