Call for papers
We welcome submissions to the 37th International Workshop on Combinatorial Algorithms (IWOCA 2026), which will be held during June 8-12, 2026, at Université Clermont Auvergne in Clermont-Ferrand, France. Since its inception in 1989 as AWOCA (Australasian Workshop on Combinatorial Algorithms), IWOCA has provided an annual forum for researchers who design algorithms for the myriad combinatorial problems that underlie computer applications in science, engineering and business.
Topics
The conference focuses on combinatorial algorithms and related areas. Topics of interest include (but are not limited to) the following:
- Algorithmic Game Theory
- Algorithmic Lower Bounds and Fine-grained Complexity
- Algorithms and Data Structures
- Algorithms for Big Data and Networks Analytics
- Algorithms for Cryptography and Information Security
- Algorithms on Graphs, Strings, and other Discrete Structures
- Approximation Algorithms
- Circuits and Boolean Functions
- Combinatorics
- Combinatorics of Words
- Combinatorial Games
- Combinatorial Generation, Enumeration and Counting
- Combinatorial Optimization
- Complexity Theory
- Computational Algebra
- Computational Biology
- Computational Geometry
- Distributed and Parallel Algorithms
- Experimental Evaluation of Algorithms
- Graph Drawing
- Graph Theory
- Mobile Agents
- New Paradigms of Computation
- Online and Streaming Algorithms
- Parameterized and Exact Algorithms
- Probabilistic and Randomized Algorithms
- Scheduling Algorithms
Submission instructions
Authors are invited to submit high-quality manuscripts reporting original unpublished research in the topics of IWOCA. Papers are to be submitted electronically through Easychair.
Simultaneous submission to other conferences or workshops with published proceedings or to a journal is not allowed. At least one author of each accepted paper must present the paper at the conference as a registered participant. For authors who cannot present their paper in person, remote presentations are possible, but the workshop will not be held online and full registration will still be mandatory.
Each submission should be in the form of a single pdf file and consist of the main part of the paper, not exceeding 12 pages in the Springer LNCS format (including the title page and excluding the references), plus an optional, clearly marked appendix (to be read at the discretion of the committee). The main body of the paper must be self-contained, in particular, any figure pertaining to the main part of the paper should be included therein (within the 12 page limit). The LNCS style should not be modified (font size, spacing and margins should follow the default of the LNCS style). The paper should not reveal the identities of the authors (see instructions for double-blind format below). Submissions not conforming to the above rules and papers outside of the scope of the conference will be rejected without consideration. Springer encourages authors to include their ORCIDs in their papers, and requires to draw the attention of the contributing conference paper authors to the Code of Conduct. Please follow Springer's guidelines.
Papers eligible for the best student paper award should be identified as "Student Paper" in the submission system by ticking the appropriate checkbox.
Double-blind reviewing
For the first time, IWOCA 2026 will employ a lightweight double-blind reviewing process: submissions should not reveal the identity of the authors in any way. The purpose of the double-blind reviewing is to help PC members and external reviewers come to an initial judgement about the paper without bias, not to make it impossible for them to discover the authors if they were to try. Nothing should be done in the name of anonymity that weakens the submission or makes the job of reviewing the paper more difficult. In particular, important references should not be omitted or anonymized. Uploading the paper to one's website or to a public repository (such as the arXiv) is permitted. Conflicts of interest with members of the programme committee must be disclosed on the submission server at the time of submission. Conflicts of interest include: being a family member or close friend, advisor/advisee (no time limit), having the same affiliation, being involved in an incident of harassment or other negative interaction (it is not required that the incident be reported or known), person who owes author a favour (e.g., recently requested a reference letter), frequent or recent collaborator (within last 5 years), and any other situation where the person may not be objective in judging the authors' work.
Proceedings and Journal Special issue
The conference proceedings will be published in the LNCS series of Springer, within the ARCoSS subline.
Authors of selected papers accepted to IWOCA 2026 will be invited to submit extended versions of their papers to Special Issues at the "Journal of Computer and Systems Sciences" and "Discrete Mathematics & Theoretical Computer Science".
Awards
Awards sponsored by Springer will be given to the best paper and the best student paper. To be eligible for the best student paper award, at least one of the authors must be a full-time student at the time of submission, and the student(s) must have made a significant contribution to the paper. The programme committee may decline to make these awards or may split them.
