GENIUS
General Environment for Negotiation
with Intelligent multi-purpose Usage
Simulation
Background
• The original purpose of GENIUS: assist in
designing of generic efficient negotiation
strategies
• GENIUS is used in education (teach design of
generic efficient negotiation strategies)
• Can be used as a testbed for automated
negotiating strategies
• Can be used in experiments with human
negotiators
• Can be used as a training environment (training
of negotiation skills)

Project Management
• Source code is stored on SVN:
https://mmi.tudelft.nl/svn/nego
• Trac:https://mmi.tudelft.nl/cgi-bin/negotiation.cgi
• Sub-projects (branches):
– GENIUS Core + GENIUS Swing GUI:
•
•
•
•
NegotiatorGUI – stable version used for ANAC (Dmytro)
GeniusBI – used by Bar-Ilan university (Yinon, )
GeniusS – main development branch (Dmytro, Tim, Colin)
NegotiatorGRID – (Crisitina, Dmytro)
– GENIUS Web
• GeniusWeb – Genius Web
– GENIUS Simulator Web
• GeniusWebSimulator – (Dmytro, Alper)
Documentation
• Available:
– User guide explaining how to use GENIUS Desktop Application
(requires minor revision):
• Installation
• Working with domains/profiles
• Explained how to make own agent (uses ZI agent as an example)
• To do:
– User guide for GENIUS Web Application
– Programmer’s guide:
• Explain GENIUS architecture
• Explain modules in details (classes, relations between classes,
interaction between objects, etc.)
– Java Doc
Technologies
• Programming language: Java, version >1.5
• Used technologies:
– GENIUS Desktop Application:
• SWING – used in GUI
• JFreeChart - used in GUI to draw charts
– GENIUS Web Application:
• J2EE (Java Enterprise Edition)
– JSP (Java Server Pages) - used to create HTML pages that are shown to a user
– Servlets – establish interaction (on the server) between user interface and GENIUS Core
– JAXB (Java Architecture for XML Binding) – used to (de)serialize objects (actions, bids) into
(from) XML format.
•
•
•
•
JavaScript – used for scripting of user’s GUI (redrawing tables, charts, etc.)
AJAX – used to make async. calls to the server without refreshing browser
Jquery – used to simplify access to AJAX and elements of the user’s GUI
Tomcat >6.0 – a server-side run-time enviroment
GENIUS in Education
• AI Techniques:
– See NegotiatorGUI\doc\assignment.pdf
– A negotiation session in the beginning
– Students design own automated strategies in
GENIUS
• Field trips (demos, summer schools, etc.)
– Install Genius Web on a laptop (server)
– take a wirred router (ask Ruud/Bart) and sufficient
number of cables
– configure the router to generate dynamic IP
– assign a static IP address to the laptop
Short-term planning
• Add a Web interface for simulations
• Extend preferences representation module to
support:
– complex utility functions (e.g., dependencies)
– hard constraints
– (qualitative preferences, e.g., CP-nets)
• Extend analytical toolbox with:
– cache for optimal solutions
– analysis of one-to-many and many-to-many
negotiations
– “re-play” of negotiations from logs
• Missing documentation
Advices
• Split GENIUS Core in a separate project
• Manage the GENIUS Core exclusively by
VICI team
• Use “extends” instead of changing the
GENIUS Core classes
• Project maintenance and development can
be delegated to:
– GENIUS Core -> Tim
– Other modules -> Wouter, Bart, Ruud
Ideas
• GENIUS Web:
– Allow long negotiations (days, weeks)
– Introduce mediator
– Extend human bidding GUI with an advice
from an agent (Tim?)
• Add new preference elicitation tools
• Choose a software license (GPL,
Apache,…)
• Make a SourceForge account?
