grobianFind reducts
The reducts of an attribute (set) can be found via this procedure.
You can set an upper and a lower value for the approximation quality as well as the stepsize. The procedure will find the reducts of the dependent attributes with respect to the independent attribute(s) up to the chosen approximation quality. The maximal number of reducts which the system will find can be set inthe lower window.

To find the proper reducts of the system just set top = down = 1 and put all attributes into the window of the independent variables.

The results will be written into the log file.
