"marvin" is a Java application to visualize fuzzy rules written in ARL (ABLE Rule Language). To read ARL files it uses the ABLE (IBM's Agent Building and Learning Environment) library. Visualization is done with JFreeChart. The output can be exported as bitmap or vector graphics, which is done by the FreeHEP framework. The application is 100% pure Java and therefore OS-independent.

Our motivation: ABLE provides a powerful agent building framework which defines a rule language, ARL. We currently focus only on the fuzzy part of this language. ABLE provides also a tool to visualize these fuzzy rules - unfortunately, these visualizations are wrong and the tool is very limited. Our main target is to develop a software which provides

• correct visualizations
• graphic export & print
• alpha cut calcuations

The project was created during our studies at the University of Applied Sciences, Rapperswil (Switzerland).
