IJCAI 2026: Human-Agent Negotiation League Call for Submissions

Deadline: June 1st, 2026

Participate in the Human-Agent Negotiation League at IJCAI 2026 by submitting your negotiating agent. Deadline for submissions is June 1st, 2026.

The International Automated Negotiating Agents Competition (ANAC) is hosting the Human-Agent Negotiation (HAN) League as part of IJCAI 2026. Participants are invited to submit negotiating agents that can effectively negotiate with human subjects using the alternating offers protocol (AOP) and multi-modal communication.

The competition will evaluate agents based on their utility against various human subjects and their perception by human partners. The league is built on NegMAS, and participants can implement their agents using multiple APIs, including a single __call__() method or by modifying LLM prompts.
