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?
