Version 6.0 of HUGIN Expert’s Bayesian network environment was released early November 2001.
The new release consists of a heavily improved HUGIN Decision Engine and a completely re-engineered graphical user interface (GUI). The new GUI runs on a range of different platforms, as it is written in Java. Moreover, the GUI contains a number of new features, including support for object-oriented construction of Bayesian networks, supporting network construction with repeated changes of level of abstraction (i.e., top-down construction, bottom-up construction, or a mix of the two). The handling of tables has also been improved, as multiple tables can be displayed simultaneously and the display of tables can be turned on and off. The new GUI also provides a powerful zooming capability, as the display of networks and monitor windows for discrete nodes can be scaled arbitrarily.
