The 11th edition of the Competition on Software Verification (SV-COMP 2022) provides the
largest ever overview of tools for software verification. The competition is an annual …

Software-verification tools sometimes produce incorrect answers, which can be a false alarm
or a wrong claim of correctness. To increase the reliability of verification results, many …

The verification community develops two kinds of verification tools: automatic verifiers and
interactive verifiers. There are many such verifiers available, and there is steady progress in …

The new version of the witness validator Symbiotic-Witch follows more precisely the (fixed
version of the) semantics of verification witnesses. This makes the tool more efficient as it …

Witch 3 is a new validator of violation witnesses in the witness format 2.0. Note that our
previous tool, Symbiotic-Witch 2, can validate only violation witnesses in the old GraphML …

Over the last years, witness-based validation of verification results has become an
established practice in software verification: An independent validator re-establishes …

Witnesses record automated program analysis results and make them exchangeable. To
validate correctness witnesses through abstract interpretation, we introduce a novel abstract …

The field of software verification has produced a wide array of algorithmic techniques that
can prove a variety of properties of a given program. It has been demonstrated that the …

Producing witnesses alongside the verdict for a verification task has become standard for
software verifiers, as it allows for automatic and independent validation of the result. This …
