IWOCA 2021

32nd International Workshop on Combinatorial Algorithms

5-7 July 2021
Ottawa, Canada (held online-only)

COVID-19 update: The conference and affiliated workshops will be online-only,
hosted by the University of Ottawa, Canada.


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.


The program committee is soliciting original and significant research contributions to the broad area of combinatorial algorithms, including (but not limited to): Algorithms and Data Structures, Algorithmic Game Theory, Approximation Algorithms, Complexity Theory, Combinatorics and Graph Theory, Combinatorial Generation and Enumeration, Combinatorial Optimization, Combinatorics of Words and Strings, Computational Geometry, Computational Biology, Cryptography and Information Security, Graph Algorithms, Graph Drawing and Labelling, Decompositions and Combinatorial Designs, Distributed and Network Algorithms, Dynamic and Evolving Networks, Mobile Agents, New Paradigms of Computation, Online Algorithms, Parallel Algorithms, Parameterized and Exact Algorithms, Probabilistic and Randomized Algorithms, Streaming Algorithms.


Abstract: March 8, 2021 (AoE)
Paper submission: March 14, 2021 (AoE)
Notification to authors: May 1, 2021
Camera-ready submission: May 13, 2021
Symposium: July 5-7, 2021

If the Covid situation allows it, IWOCA 2021 will take place in Ottawa, Canada. Otherwise, it will be held virtually or in some hybrid form.


Authors are invited to submit high-quality manuscripts reporting original unpublished research in the topics related to the symposium. Simultaneous submission to other conferences or workshops with published proceedings is not allowed. It is required that each accepted paper be presented at the conference by one of its authors.
Submissions must be in the form of a single pdf file prepared using the LNCS latex templates and style files. Springer’s proceedings LaTeX templates are also available on Overleaf. Springer’s authors’ guidelines may be consulted at the following link:
Each submission should consist of the main part of the paper, not exceeding 12 pages (including the title page and excluding the references), plus an optional clearly marked appendix (to be read at the discretion of the program committee). Any figure pertaining to the main part of the paper should be included therein (within the 12 page limit). The first page must include an indication of whether the paper is eligible for the best student paper award. Papers are to be submitted electronically through EasyChair at the following link:


- Maria Chudnovsky, Princeton University, USA
- Anna Lubiw, University of Waterloo, Canada
- David Peleg, Weizmann Institute of Science, Israel
- Alfred Wassermann, Universität Bayreuth, Germany


Conference proceedings will be published in the ARCoSS subline of the Springer "Lecture Notes in Computer Science" series.


Selected papers will be invited to a special issue of the Springer journal "Algorithmica", devoted to IWOCA 2021. (


Awards 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 paper 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.
