PLDI 2024
Mon 24 - Fri 28 June 2024 Copenhagen, Denmark

Research on and around e-graphs has recently exploded in both quantity and diversity. The data structure that powers SMT solvers is now seeing use in synthesis, optimization, and verification via equality saturation and related techniques. In addition to recent advances in the core data structure and techniques, researchers and practitioners are applying e-graphs to domains such as compilers, floating point accuracy, test generation, computational fabrication, automatic vectorization, deep learning compute graphs, symbolic computation, and more.

The third EGRAPHS workshop will bring together those working on and with e-graphs, providing a collaborative venue to share work that advances e-graphs as a broadly applicable technique in programming languages or other fields of computing. The program will contain a mix of invited speakers and work-in-progress talks. The symposium seeks papers on a diverse range of topics including (but not limited to):

  • e-graphs as data structures and their related algorithms
  • equality saturation and other e-graph based rewriting approaches
  • applications of e-graphs and/or equality saturation, whether in programming languages or other fields
  • tools/frameworks that facilitate the use of e-graphs and associated techniques
  • investigations into the human-facing aspects using e-graph-based toolkits including error reporting, debugging, and visualization
  • other frameworks for optimizing/analyzing programs in an equational manner

Accepted submissions will not be placed on the ACM DL, so we allow and encourage in-progress or already published relevant work to be presented.

Call for Presentations

We invite submission for talks broadly, including talks that may cover already published or in-progress work. Submissions should be in the form of a 2 to 6 page extended abstract that describes the key problems addressed and/or reusable insights from the proposed talk. Links to preprints, repos, demos, or other media are encouraged!

We welcome submissions from academic, industrial, or independent researchers and practitioners. Talks are intended to foster discussion between members of the e-graph community. The program will include time for Q&A as well as open-ended discussion inspired by the talks.

Submissions and review will take place on HotCRP. Submissions are not anonymous.
