The Algorithms and Data Structures Symposium, WADS, which alternates with the Scandinavian Symposium and Workshops on Algorithm Theory, SWAT, is intended as a forum for researchers in the area of design and analysis of algorithms and data structures.

WADS 2025 will take place August 11-15, 2025 at York University in Toronto, Canada. CCCG 2025, the 37th Canadian Conference on Computational Geometry, is planned for August 11-15 at the same location.

We invite submissions of papers presenting original research on the theory and application of algorithms and data structures in all areas including, but not limited to: approximation algorithms, parametrized algorithms, distributed algorithms, parallel algorithms, external-memory algorithms, data structures, computational geometry and topology, exponential time algorithms, online algorithms, randomized algorithms, streaming algorithms, sub-linear algorithms. The algorithmic problems considered may be motivated by applications, e.g. in optimization, graph analysis, bioinformatics, visualization, string processing, information retrieval, machine learning, algorithmic game theory, or mechanism design.

WADS participates in SafeToC and is committed to preventing and combatting harassment in the Theory of Computing community. The ToC advocate for WADS is Pat Morin. Authors who submit papers will have an opportunity to declare a conflict of interest with potential reviewers.

WADS 2025 will have a best paper award in memory of Alejandro Lopez-Ortiz and a best student presentation award. The paper that receives the memorial award will be presented in a non-parallel time slot. The best student presentation will be chosen by a subset of the program committee with input from session chairs.

Submission Guidelines

All papers must be original and not simultaneously submitted to another journal or conference. Contributors are invited to submit a full paper in LIPIcs format. The title, abstract, and body of the paper may not exceed 12 pages and the total length including references may not exceed 14 pages. An appendix, beyond the 14 pages, may be added and may be read at the reviewers’ discretion. Submissions will be handled through EasyChair https://easychair.org/conferences/?conf=wads2025. For further information, see the WADS 2025 website.
