Dear colleagues, We are thrilled to announce that the ROADEF/EURO 2026 Challenge is officially open! This year's edition, titled "Keep the Flow!", focuses on the optimization problem of T-Adaptive Segment Routing (T-ASR). Proposed by Orange Research, the challenge invites participants to design efficient optimization algorithms for routing in large-scale telecommunication networks, taking into account scheduled maintenance interventions and reconfiguration budgets. Watch the official teaser for a quick overview of the problem: https://youtu.be/D1jubmosffI?si=tHLxgXFQkhauTjok Key resources already available: Detailed subject description: full technical specifications. Initial dataset (Set A, for the sprint phase): to begin testing your algorithms. Solution checker: a C++20 tool to validate your results. Networktools Library: A fast header-only C++20 library for modeling and solving network optimization problems. Prizes & Participation: The competition is endowed with a total prize pool of €35,000, with categories for best teams, junior researchers (students), and scientific contributions. Find all information regarding rules, organization, and the roadmap (Sprint, Qualification, and Final phases) at https://roadef.org/challenge/ We look forward to your innovative solutions and wish you the best of luck! Sincerely, The ROADEF challenge team: Zacharie Ales, Ronan Bocquillon, Eric Bourreau, Safia Kedad-Sidhoum, David Savourey. The Orange Research challenge team: Amal Benhamiche, Yannick Carlinet, Morgan Chopin, Éric Gourdin, Nancy Perrot.

Call for abstracts (DEADLINE EXTENSION)- ECCO XXXIX-CO 2026 joint Conference on Combinatorial Optimization
by Luis Eduardo Neves Gouveia 14 Mar '26

14 Mar '26

Dear Colleagues, Due to numerous requests the deadline for submissions for the ECCO XXXIX - CO 2026 joint Conference on Combinatorial Optimization is extended to NEW Abstract submission deadline: March 28 , 2026 The CO XXXIX - CO 2026 joint Conference will take place on May 14-16, 2026 in Lisbon, Portugal. ECCO (the European Chapter on Combinatorial Optimization<https://en.wikipedia.org/wiki/European_Chapter_on_Combinatorial_Optimization>) is a Working Group of EURO (the Association of European Operational Research Societies<https://www.euro-online.org/web/pages/1/home>) that provides an excellent opportunity to discuss recent and important issues in Combinatorial Optimization and its applications. CO series of biennial symposia, the Combinatorial Optimization Conferences, started in the UK in 1977 with meeting venues alternated between the UK and continental Europe. Keynote speakers: William Cook, University of Waterloo Gabor Galambos, University of Szeged Joerg Kalcsics, University of Edinburgh Sergio Garcia Quiles, University of Edinburgh We invite researchers interested in the following areas to submit an abstract: * theory and applications of combinatorial optimization; * optimal solution methods, approximation algorithms and heuristics for combinatorial optimization problems; * integer programming, global optimization, stochastic integer programming, multi-objective programming, graph theory and network flows; * application domains include, but are not limited to: logistics and supply chain optimization, manufacturing, energy production and distribution, land consolidation, telecommunications, bioinformatics, finance.
