Genius 7.1.1 (download)

New option:  You can disable the progress-chart in the multilateral single-session negotiation.
Bugfix: We now check the bid contained in an Accept.

Genius 7.1.0 (download)

- The new init method of the AbstractNegotiationParty method adds a persistance storage parameter.
- The Accept and Offer methods have extra parameters.
- TimeLineInfo class has been moved to negotiatior.timeline.

This has consequences for the backward compatibility of agents.
The agents in the repository have been adapted to work with these changes.

Genius 5.1.1 (download)

This is the official release for ANAC 2014.

+ Users are now able to change the reservation value and discount factor of non-linear scenarios using the graphical user interface.

+ Bugfix: Windows users can now also load agents into the repository through the user interface from anywhere in their file system.


Genius 5.1 (download)

+ Genius now supports non-linear negotiation scenarios. In these scenarios, the agents no longer have linear utility functions; instead, they can only sample their utility of a bid through the getUtility() method. In terms of the API, this means the agents no longer have access to methods pertaining to linear scenarios (e.g., getWeight()). The agents have to search the utility space bid-by-bid, using the getUtility() method for any bid they are interested in.

+ Bugfix: users can now load agents into the repository through the user interface from anywhere in their file system.


Genius 4.2 (download)

This release incorporates all agents and domains introduced in ANAC2013.


Genius 4.1.1 (download)

This minor release of Genius is designed for ANAC 2013. If you experience any problems please contact us.

Changelog:

+ Added capability for an agent to save and load data

For the ANAC2013 the ability to store and load information was added.

+ Changed implementation of discount

Previously, a preference profile without discount had a discount of 0.0, but now, a domain without discount has discount 1.0, which is more consistent. Also the method isDiscounted() has been added to test whether the preference profile features a discount.

+ Improved agent loading

Loading an agent has been improved in this version by providing better feedback when an error occurs.

+ Added BOA repository in GUI

BOA framework compatible agents can now be more easily added by using the BOA repository available in the GUI.

+ Validation of scenarios

Scenarios are now automatically validated to avoid errors leading to unpredictable outcomes.


Genius 4.0 (download)

This major release of Genius incorporates many new features. If you experience any problems please contact us.

Changelog: 

+ All ANAC 2010, 2011, and 2012 agents and domains are included

All ANAC agents and domains can now be used in a tournament.

+ The BOA framework has been added

The BOA framework allows to separately implement the bidding strategy, acceptance strategy, and opponent model of an agent. This allows to reuse and recombine a large set of existing components derived from price winning ANAC agents.

+ Improved documentation

Documentation has been added of the core classes and the manual has been rewritten. + Added rounds-based timeline The type of timeline can now be changed between continuous and rounds-based. In addition, the length of the negotiation can be specified.

+ Added tournament options

A tournament can now be given a large set of options, including the possibility to run without GUI and use a large set of quality measures.

+ Added a large set of quality measures A large set of quality measures have been added which can be specified in the tournament options. Examples include trajectory analysis and analysis of the accuracy of an opponent model.

+ New GUI design The GUI has been redesigned, allowing to more easily add new agents and scenarios.

+ Support of linear issues Critical bugs in the support of linear issues have been resolved.

+ Distribute a tournament over multiple computers A so called distributed tournament can be specified. This feature allows to divide a single large tournament among multiple computers.


Genius 3.2.1 (download)

Used in ANAC 2012, The Third International Automated Negotiating Agent Competition.

For ANAC 2012, we have extended Genius with a classic feature in negotiation that was absent in previous years, namely reservation values. A reservation value is a real-valued value that sets a threshold below which a rational agent should not accept any offers. Intuitively, a reservation value is the utility associated with a Best Alternative to a Negotiated Agreement (BATNA). A reservation value is the utility that an agent will obtain if no agreement is realized in a negotiation session. This can happen either by breaking off the negotiation (a non-zero reservation value makes breaking off potentially interesting) or by not reaching an agreement before the deadline associated with a negotiation session (if such a deadline is present). Reservation values typically are different for each of the negotiating agents that negotiate in a session. In case no reservation value is set in a profile, the reservation value of an agent is set to zero (0). Given that utilities for outcomes range from 0 to 1, this essentially is the same as having no reservation value. If a discount factor is present, reservation values will be discounted in exactly the same way as the utility of any other outcome.

Changelog:

+ All ANAC 2011 resources are included

All agents and negotiation scenarios of ANAC 2011 are included in the repository of this release.

+ User Interface Improvements

Many improvements have been made to the GUI, including highlighting of the last bid, an improved depiction of the outcome space, and a more user-friendly selection panel of the scenarios, agents, and protocols.

+ Previous tournament setup is remembered

The tournament setup is automatically saved every time you run a tournament.

+ Multiple sessions

It is now possible to run multiple instances of the same negotiation session.

+ Better logging

It is possible to save negotiation logs to .xml format. Negotiation features that can be logged include: time of agreement, number of exchanged bids, negotiation domain and preferences, opponent information, and distance of agreement to Nash and Pareto.

Used in ANAC 2011, The Second International Automated Negotiating Agent Competition.

Changelog:

+ Changed protocol so that agents now have a shared time line of 3 minutes

The real-time deadline of ANAC is considered to be a challenge for the competitors. In 2010, the agents had three minutes each to deliberate. This means agents have to keep track of both their own time and the time the opponent has left. For ANAC 2011, we have chosen a simpler protocol where both agents have a shared time window of three minutes.

+ Discount factors

ANAC 2011 will have domains that have discount factors. In ANAC 2010, almost every negotiation between the agents took the entire negotiation time of three minutes each to reach an agreement. Adding discount factors should provide more interesting negotiations with faster deals. The implementation of discount factors is as follows. We have added a method to UtilitySpace that gives the discounted utility:

public double getUtilityWithDiscount(Bid bid, Timeline timeline) and a convenience method in Agent that does the same thing:

public double getUtility(Bid bid)

Its definition is as follows. Let d in (0, 1) be the discount factor. (If d<= 0 or d>= 1, we assume that d = 1.) Let t in [0, 1] be the current normalized time, as defined by the Timeline. We compute the discounted utility discountedUtility as follows: discountedUtility = originalUtility * d^t. Note that for t = 0, or d = 1, the utility remains unchanged. When we use normalized time, then for t = 1 the original utility is multiplied by the discount factor. The effect is almost linear in between.
