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. In the tradition of past editions, the conference will be followed by a collaborative workshop.
The topics of interest include combinatorial algorithms and related areas, including (but not limited to) graphs, words, games, geometry, combinatorial optimization, complexity theory and models of algorithms such as exact, parameterized, distributed, online, approximation and probabilistic.
***Venue***
Clermont-Ferrand lies in the heart of France and is surrounded by a beautiful (non-active) volcanic range featuring multiple hills, mountains and lakes, to which various hiking trips can be arranged. Clermont-Ferrand is accessible by train, bus or plane via Paris and Lyon international airports.

***Registration***
IWOCA 2026 will consist of a conference, held on June 8-11, followed by a collaborative workshop, held on June 11-12. Thanks to our sponsors, the registration fee covers the whole event (and thus we encourage all participants to stay for the collaborative workshop), and entitle you to lunches, coffee breaks, social event and conference dinner.
Early registration is available until May 11, 2026, with fees of 275€ for student participants and 385€ for other participants.
Late registration will be available from May 12 to May 24, 2026, with an additional 110€ cost.

***Extended Stay Support Scheme (ESSS)***
We encourage IWOCA 2026 participants to use the opportunity of traveling to France to plan a research visit to a French institution reachable without plane, before or after IWOCA 2026. The partner institutions will partially cover accomodation, living expenses and non-plane travel fees for selected participants. Research units from Clermont-Ferrand, Lyon, Marseille, Montpellier, Nice, Orléans and Paris are participating in the scheme.
All information about the scheme and the application process can be found here:
https://iwoca2026.limos.fr/extended_stay.php
For any issue or question during the registration process, about the conference, or about the ESSS, please contact us at iwoca2026@limos.fr
We hope to see you soon in Clermont-Ferrand!
