All participants in ANAC 2024 are encouraged to upgrade to this version.

ANAC 2024 Release

This is the first official release for the ANAC 2024 competition.

This release adds Cartesian Tournaments which will be used by the ANL league and includes various bugfixes and performance improvements.

ANAC 2023 first draft release

First release for ANAC 2023

This release includes all the components and interfaces needed to run ANL 2023 and SCML 2023. The most important changes are adding cartesian_tournament() to run simple negotiation tournaments and supporting externally defined actions in all mechanisms to support using RL in SCML 2023.

For participants in ANAC 2023, it is ALWAYS recommended to use the latest version of negmas and whatever other libraries you are using in you development for the competition.

Preparing to support exposition for RL libraries

removing offer from SAO's respond() method.
allowing users to step worlds from the point of view of a set of agents ignoring simulation step boundaries and passing external actions if needed. See World.step() for details.

Generalized Bargaining and Simplified Interfaces

This version adds support for python 3.11 and drops support for python 3.8 and 3.9
We introduce a generalized form of bargaining and prepare for a major release (0.10) in which developing new agents and negotiators will be much simplified by allowing users to just use a single function for negotiators, reducing dependence on controllers and other simplifications.

v0.9.3 minor update

Better Synchronized Negotiations

This release adds two features:

2. Initial implementation of a negotiation-only tournament to easily test negotiation strategies without the need to construct worlds for them. See create_neg_tournament().
