EUROPA Documentation

If you don't know where to start, or just want a quick overview of how to use EUROPA, take a look at the EUROPA Quick Start. You can also find an overview of the EUROPA framework and philosophy at Europa Background.

Architecture

• Overview
• Propagation Services
• Plan Database Services
• Modeling Services
• Problem Solving Services
• Ancillary Modules

Development Tools

• How to embed EUROPA in an application
• makeproject: Automatically create all the pieces for a new project.
• EUROPA UI Options:
  • Eclipse Plugin (SWT): Edit NDDL, view schema, configure and run solver, and view solution details, all from within your Eclipse IDE.
  • Java PSUI (Swing): View schema, configure and run solver, interact with EUROPA, and view solution details from a plain Java UI.
  • Java UI (Swing, deprecated): another set of Java UI components, currently being merged with PSUI.
• Low-level debugging:
  • EUROPA Logging
  • Timelines
  • The Token Network
  • The Constraint Network
  • Metric Resources
  • Common Debugging Scenarios

EUROPA Components

• API [is the Client API and the recommended way to embed EUROPA into and application. This interface is also available in Java (we use http://www.swig.org SWIG to do the mapping automatically).
