ANAC 2027 is being prepared. The host conference, the call for participation and all submission deadlines will be published here as soon as they are confirmed. Register to be notified when submission opens. The previous edition, including every league's final results, is archived at ANAC 2026.

The Automated Negotiating Agents Competition has run every year since 2010 and returns for its 18th edition in 2027. The host conference and venue are to be announced.

What is already known: ANAC 2027 is expected to run the same leagues as 2026 — the Automated Negotiation League (ANL), the Supply Chain Management League (SCML) and the Human-Agent Negotiation League (HAN) — alongside the new Hybrid Intelligence (HI) League. Rules, tracks and prizes for each league are confirmed with the CFP.

Leagues in ANAC 2027

ANL

Automated Negotiation League

Explore the strategies and difficulties in creating efficient agents whose primary purpose is to negotiate with other agents' strategies.

Details Results 2026
SCML

Supply Chain Management League

Design and build an autonomous agent that negotiates on behalf of a factory manager situated in a supply chain management simulation.

Details Results 2026
HAN

Human-Agent Negotiation

Build a negotiation strategy that uses the alternating offers protocol (AOP) augmented with text input / output to effectively bargain against human subjects. Agents may use multi-modal communication to influence or inform their human counterpart.

Details Results 2026
HI · New

Hybrid Intelligence

Build an agent that negotiates with a human partner rather than against one: the two form a single negotiating team facing a third party, and are scored on what the team achieves together.

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.
