*** Last Call for Workshop and Competition Proposals *** The 25th International Conference on Autonomous Agents and Multiagent Systems (AAMAS 2026) May 25-29, 2026, 5* Coral Beach Hotel & Resort, Paphos, Cyprus https://cyprusconferences.org/aamas2026/<http://www.cs.ucy.ac.cy/~george/GPLists_2021/lm.php?tk=YWlyLWwJCQlhaXItbEBsaXN0c2Vydi5hb2lyLm9yZwlUaGUgMjV0aCBJbnRlcm5hdGlvbmFsIENvbmZlcmVuY2Ugb24gQXV0b25vbW91cyBBZ2VudHMgYW5kIE11bHRpYWdlbnQgU3lzdGVtcyAoQUFNQVMgMjAyNik6IExhc3QgQ2FsbCBmb3IgV29ya3Nob3AgYW5kIENvbXBldGl0aW9uIFByb3Bvc2Fscwk0NDAJQUFNQVMyMDI2CTE3OAljbGljawl5ZXMJbm8=&url=https%3A%2F%2Fcyprusconferences.org%2Faamas2026%2F> AAMAS 2026 received 1455 full paper submissions for the Main Track, after an initial submission of 1800 abstracts. This is by far the highest number of submissions (around 50% more than the previous highest number) in the 25 years of AAMAS. Workshops AAMAS 2026 invites proposals for the workshop program, which will be held on May 25-26, 2026, immediately before the main program of the AAMAS conference. The objectives of the AAMAS 2026 workshop program are to stimulate and facilitate discussion, interaction, and comparison of approaches, methods, and ideas related to specific topics, both theoretical and applied, in the general area of Autonomous Agents and Multiagent Systems. The AAMAS 2026 workshops will provide an informal setting where participants will have the opportunity to discuss specific technical topics, fostering the active exchange of ideas and supporting community development. We invite the submission of workshop proposals for review. We encourage workshops proposals that focus on emerging topics, open research questions and challenges, as well as broader subjects of interest to a wider community. Additionally, we welcome workshops with previous editions at AAMAS that can attract established communities working in the same research area. Workshops may vary in length from half a day to two days, though most are expected to last one full day. Attendance will be limited to registered participants, and both organizers and attendees must register for their workshop, which will have a separate fee from the main conference. Workshop attendees are not required to register for the main AAMAS conference if they do not plan to attend it, though this is highly encouraged. AAMAS 2026 will be an in-person event in Paphos, Cyprus. AAMAS 2026 reserves the right to cancel workshops if the registration numbers do not cover their operating costs. Competitions We are glad to announce the third edition of the AAMAS Competition track at AAMAS 2026. Competitions are an effective mechanism for motivating researchers to enhance discussions, share knowledge, and boost the development and evaluation of theory and practice of autonomous agents and multiagent systems. By proposing challenging competitions to the AAMAS community, competition proposers contribute to pushing the state-of-the-art in specific areas or to solving problems of practical importance. We invite competition proposals on topics of interest to the AAMAS community. We encourage submissions from emerging areas or novel application scenarios relevant to the AAMAS community. Submissions from established areas for which the competition may serve as a stimulus to advance theory and practice or renew the interest of young researchers in the area are also welcome. We highly value interdisciplinary topics that have the potential to attract a significant cross-section of the community. If the accepted competition involves the development of tools and platforms for supporting agent development, the proposer(s) will be encouraged to submit a Demonstration paper at AAMAS 2027 summarizing the design, development, and outcomes of their competition at the 2026 conference. At least one proposer of each accepted competition is required to register and attend the conference to run the finals of the competition and/or to announce the winners.
