Quantifiers play an important role in language extensions of many logics. The use of quantifiers often allows for a more succinct encoding as it would be possible without quantifiers. However, the introduction of quantifiers affects the complexity of the extended formalism in general. In consequence, theoretical results established for the quantifier-free formalism may not directly be transferred to the quantified case. Further, techniques successfully implemented in reasoning tools for quantifier-free formulas cannot directly be lifted to a quantified version.

The goal of the Workshop on Quantification (QUANTIFY 2024) is to bring together researchers who investigate the impact of quantification from a theoretical as well as from a practical point of view. Quantification is a topic in different research areas, e.g., in SAT in terms of QBF, in CSP in terms of QCSP, in SMT, etc. This workshop has the aim to provide an interdisciplinary forum where researchers of various fields may exchange their experiences.

In particular, the following topics shall be considered at the workshop:

  • Theoretical aspects of quantification

  • Practical aspects of quantifications

  • Intersections between the different research communities working on quantification


The workshop is concerned with all theoretical and practical aspects of quantification in logics such as QBF, QCSP, SMT, and theorem proving. The topics of interest include (but are not limited to):

  • Complexity results

  • Encodings with and without quantification and comparisons thereof

  • Applications of quantification

  • Implementations of reasoning tools

  • Case studies and experimental results

  • Intersections between the different research communities working on quantification

  • Surveys of state-of-the-art approaches to handling quantification


Submissions of extended abstracts, full papers, and tutorials are solicited and will be managed via Easychair:

Submitted papers should be formatted in LNCS format.

We solicit three types of submissions:

  • Talk abstracts (maximum two pages, excluding references) describing already published results.

  • Full papers (maximum 15 pages, excluding references) on novel, unpublished work.

  • Tutorial papers (maximum 15 pages, excluding references) introducing a research field related to quantifiers.

The talk abstracts should include a relevant bibliography of related work and an outline of the planned talk. For this category, we explicitly advocate talks which summarize the results of one or more already published papers.

Full papers should contain novel, unpublished work that qualifies to be published in a special issue of a journal or formal workshop proceedings. The 15 pages are an upper limit, shorter papers are also welcome.

Tutorial papers should survey results already published, maybe in multiple articles or presentations capturing the commonalities and differences of various quantification approaches (perhaps even interdisciplinary).

Each submission will be assessed by the program committee and the workshop organizers with respect to novelty, originality, and scope.

Submissions related to completed work as well as work in progress are welcome. Authors are encouraged to provide additional material such as source code of tools, experimental data, benchmarks and related publications in an appendix or a related webpage. The additional material will be considered at the discretion of the reviewers.

Previously published work or extensions thereof may be submitted to the workshop but that case has to be explicitly stated in the submitted paper. This regulation also applies to work which is currently under review elsewhere.

Authors of accepted abstracts and papers are expected to give a talk at the workshop.

The outcomes of the discussions will be summarized in a workshop report, which can be made publicly available as technical report (unless the participants decide not to do so).

In case we get enough full and tutorial papers, we will organize a special issue on quantification (e.g., in the Journal of Satisfiability (JSAT) or formal workshop proceedings.
