About the Conference
The International Conference on Optimization and Information Systems (COSI) aims to bring together researchers in Computer Science and Applied Mathematics, particularly in the areas of combinatorial optimization, graph theory, information systems, and artificial intelligence.
The 17th edition of COSI, hosted by the Faculty of Mathematics and Computer Science at the University of Batna 2, will take place from May 12 to 14, 2026. This event continues the series of previous editions held in Tizi-Ouzou (2004), Béjaïa (2005), Algiers (2006), Oran (2007), Tizi-Ouzou (2008), Annaba (2009), Ouargla (2010), Guelma (2011), Tlemcen (2012), Algiers (2013), Béjaïa (2014), Oran (2015), Sétif (2016), Bouira (2017), Oran (2018), Tizi-Ouzou (2019) and Béjaïa (2025), following a brief interruption due to the Covid-19 pandemic.
COSI fosters a friendly and stimulating environment for discussions and collaborations among researchers from all over the world. Continuing its tradition, the 2026 edition will feature high-profile invited talks, original research papers, and demonstrations of research prototypes.

Accepted and presented papers will appear in the online conference proceedings. Discussions are ongoing with Springer to publish post-conference proceedings in the CCIS series, indexed in major databases such as DBLP, Google Scholar, EI-Compendex, Mathematical Reviews, SCImago, and Scopus. CCIS volumes are also eligible for consideration in special issues.
Conference Topics
COSI 2026 is organized around five main tracks, with a non-exhaustive list of related keywords. This edition particularly encourages interdisciplinary papers that integrate methods and concepts from multiple scientific domains. Many research problems today require expertise spanning several fields — such as astrophysics, molecular chemistry, biology, and social sciences — in close interaction with computer science. Artificial intelligence, big data analytics, and optimization or decision-support algorithms often form the cornerstone of such interdisciplinarity.
