General Information

ANAC dedicates to develop successful automated negotiators for scenarios where there is incomplete information about the opponent. The design of generic negotiating agents aims to operate in a variety of scenarios providing benchmarks of performance.

GENIUS (General Environment for Negotiation with Intelligent multi-purpose Usage Simulation) is a negotiation environment that implements an open architecture for heterogeneous negotiating parties. In addition, Genius can be used to implement, or simulate, real life negotiations.

Setup

• Java Integrated Development Environment (Eclipse IDE)
• Java Version 8
• Genius.XXX version

How to run

Genius can run on any machine running Java 8. Java 9 is not yet supported.

1. Download the file genius-XXX.zip from http://ii.tudelft.nl/genius/?q=article/releases and unzip it to your machine.

2. Install the environment, the file genius-XXX.zip.

• genius-XXX.jar => GENIUS negotiation simulator

3. Start a console and find the directory of genius-XXX.jar
   • On windows, open the .jar using java -jar genius-XXX.jar
   • On mac, open the .jar using
     
     • Systemdisk/Applications/Utilities/Console.app
     • Double click on the app on the path above

For more information, check readme in the genius folder.

Connect IDE & Genius

1. Open Eclipse

2. Select File->New Java Project

   • Make sure you select JavaSE-1.8. If you missed JavaSE, you can download it from https://www.oracle.com/java/technologies/downloads/#java17

3. Import (or drag) genius-XXX.jar into the project in the navigator area

4. Connect genius Jar - Right click on the <your_project_name> icon and select ”Properties”. - Select the Java Build Path. - Select the Libraries Tab. - Select ”Add JARs”, in the JAR Selection window.
   - Open the <your_project_name> folder, scroll down to select genius.jar and run as java application .

Create An Agent

• Drag an example folder from your unzipped genius
• Drop it on the src folder
• Copy files and rename folder
• Work using imagination and check out other agents policy to enrich yours.

Execution

There are two modes to run a negotiation:

• Session

• Tournament

  

In each mode, parameters need to be specified for running.

Log files

Log files get the filename tournament- followed by day and time followed by the domain name and an extension.
There are 3 log files:
