===================================================
Platforms: 32-bit windows systems on PC (Windows 95 /98 /NT).

Version: 2.0 Beta

Input: A data set with discrete values in all fields (attributes) and
optional domain knowledge (attribute ordering, partial ordering, 
direct
causes and effects (initial structure), forbidden links, root and leaf
nodes.)

Output: The belief network (including both structure and parameters) 
of the
data set.

Main Features:
User_friendly interface & Graphical BN editor;
Accessible to many data set formats, support condensed data sets;
Using efficient BN learning algorithms to support large data sets: in
practice, the running time is linear to the number of records and 
about
O(n^2) to the number of attributes (n is the number of attributes).
The learned belief networks can be saved into Hugin and Netica 
formats.
The construction engine can be integrated into other win32 based 
systems
through API function calls.
