Rule generation

    1-1 rules

You have the possibility to generate all exact and approximate 1-1 MP-rules (A1=>A2) satisfying the eventually filters.
For this option, simply don't tick the "rule degree" box.

    n-1 rules

You can also choose to infer a subset of n-1 MP-rules (e.g. A1A2=>A3).
In this case, the exact MP-rules with the smaller left hand sides and the approximate MP-rules with the larger left hand sides satisfying the eventually filters are generated.

The degree corresponds to the max number of attributes in the left hand side of the rules.

Remark: The exact rule empty=>Y means that Y always occurs.
