• May 21st, 2026 Participant home page now has Stats and Charts tabs covering every ANAC league you submit to (SCML Standard / OneShot, ANL, HAN) — runs, best/mean/latest score, best rank, exception totals, plus score-over-time line charts.
• May 19th, 2026 Starting May 21st, 2026 we will enforce Python naming conventions on every new submission across all leagues. Agents / negotiators whose class name is the placeholder MyAgent or MyNegotiator — or whose module path contains the segments myagent or mynegotiator — will be rejected by the submission form and excluded from official tournament runs. Please pick a unique PascalCase class name (e.g. TeamXAgent for SCML, MyTeamNegotiator for ANL/HAN) and a lower_snake_case dotted module path (e.g. teamx.strategy) before re-uploading. If you submitted with the default placeholder names, you should have received an email with the details — reply to that email if you need help.
• May 7th, 2026 The submission deadline has been extended to June 15th, 2026 for all leagues.
• February 6th, 2026 The submission site is now ready for submissions. Welcome to ANAC 2026!

Overview of ANAC

The Automated Negotiating Agent Competition (ANAC) is an international tournament that has been running since 2010 to bring together researchers from the negotiation community. ANAC provides a unique benchmark for evaluating practical negotiation strategies in multi-issue domains and has the following aims:

• to provide an incentive for the development of effective and efficient negotiation protocols and strategies for bidding, accepting and opponent modeling for different negotiation scenarios;
• to collect and develop a benchmark of negotiation scenarios, protocols and strategies;
• to develop a common set of tools and criteria for the evaluation and exploration of new protocols and new strategies against benchmark scenarios, protocols and strategies;
• to set the research agenda for automated negotiation.

The previous competitions have spawned novel research in AI in the field of autonomous agent design which are available to the wider research community.
