<https://roar-net.eu/calls/code-fest-call/>

From 18:00 CEST (UTC+2, Brussels) on 9 September 2025 to 18:00 CEST on 11 September 2025.

The ROAR-NET Problem Modelling Code Fest is a 48-hour online coding event running from 18:00 CEST (UTC+2, Brussels) on 9 September 2025 to 18:00 CEST on 11 September 2025. It will also be held locally at physical hubs organised by volunteers around the world, with the schedule taking the relevant time zones into account.

Why participate? 

Participants in the Code Fest will learn how to use the ROAR-NET API to develop computational models of combinatorial optimisation problems in a solver-agnostic way. They will also have the opportunity to get involved in the ROAR-NET community and contribute to the ongoing development of the API, associated methodology, and supporting tools, by making open-source/open-access code and non-code contributions to the ROAR-NET repositories.

Programme highlights:

* Kick-start presentations on optimisation, problem modelling, the ROAR-NET API Specification and its implementation in Python

* Live-coding modelling tutorials

* Q&A sessions

* A Training Track, consisting of a sequence of modelling challenges to be completed using the ROAR-NET API by teams of 1-4 participants

* A Development Track, consisting of problem-statement development, model implementation, benchmark-instance construction, and software-tool development activities, to be proposed and carried out by teams of any size

* Badges awarded to teams for concrete achievements

* Achievement board updated throughout the event
