The submission deadline for the first version of the solvers is on Jun 18. However, it is useful for the organizing team to know in advance which and how many solvers may be entering. If you have not submitted a solver before, or if you think there may be unusual circumstances, please let us know at your earliest convenience if you think you may be submitting a solver to SMT-COMP’22. We require a system description for all submitted solvers as part of the submission of the final solver versions (deadline Jul 2).
The parallel and cloud tracks will again run on AWS, which is kindly supporting them. Participants of these tracks are required to submit their solver via a GitHub repository (which can be private). The repository should contain a docker file that compiles the solver. Detailed instructions for submitting to these tracks are available in this link (they lift to SMT).
To participate teams must email firstname.lastname@example.org with the following:
We have a few central changes to the competition rules with respect to previous years.
In this track teams can submit proof-producing solvers together with proof checkers for their proof formats. We will compile and present the results, as well as assemble a panel of non-organizer experts to do a qualitative assessment for each proof-producing solver, proof format, and proof checker.
The benchmark selection is simplified by using a unique way to select elements from a set. For example randomly selecting n problems from a set of problems is done by shuffling a list of the problems and selecting the first n. So if there are less than n problems, they are all selected. The complete selection is first done by selecting in each category in each logic, then selecting the resulting set in each category. At the end 400 benchmarks are selected.
Unknown benchmarks that were confidently determined to be sat or unsat during the single query track will be used in the model validation, unsat core and proof exhibition tracks.
The quantifier free logics with datatypes (QF_UFDT and QF_DT) will become their own division, moving out of the QF_Equality division. Moreover, non-competitive logics will not run even if they are in competitive divisions.
We will add to the model validation track quantifier free logics with floating points. So QF_FP and the combination with other supported theories (QF_UFFP, QF_BVFP, etc.), which are a subset of the QF_FPArith division. This division will be experimental. We are also changing the model validator from pysmt for Dolmen, which is a better long-term solution, both for maintenance and for scalability.
