Automated Negotiating Agents Competition (ANAC2020)

To be held as part of the IJCAI2020 competition challenge

NEWS (May 29th, 2020)

COVID-19 update - New submission deadline: 14th July, 2020.

ANAC 2020 will go ahead, with more than 70 registered participants so far. ANAC will be held in conjunction with IJCAI 2020, which will be held in January 2021. The deadline for submitting agents to each ANAC league is postponed until 14th July, 2020. The winners of each league will be announced in January 2021 during IJCAI - either live or digitally. We will announce a set of finalists in August 2020 (tentative). A select number of finalists will be invited to publish their agent descriptions in the Journal Knowledge Engineering Review. We aim to provide student support to travel to IJCAI. We as the ANAC board are working hard to manage the current situation and will continue to keep you updated as we learn more.


Overview of ANAC2020

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.

This year, we introduce five different negotiation research challenges:

We expect innovative and novel agent strategies will be developed, and the submitted ANAC 2020 agents will serve as a negotiating agent repository to the negotiation community. The researchers can develop novel negotiating agents and evaluate their agents by comparing their performance with the performance of the ANAC 2020 agents.

Leagues in ANAC2020

Automated Negotiation League

Representing users in a negotiation: developing an agent that can negotiate while performing preference elicitation.

Human-Agent League

Explore the strategies, nuances, and difficulties in creating realistic and efficient agents whose primary purpose is to ‚Äčnegotiate with humans.‚Äč

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.

Werewolf Game League

Build an agent that is able to build consensus with other actors (who are potentially deceptive), identify agents of the opposing team and coordinate to vote them out of the game.


Render as avatars on a display, and the human interacts with them by speaking (in English) and looking at the one with whom they wish to negotiate.
