- Two new genetic operators
- AddAlternative - generalizes constraints by changing a 0 to a 1
- in an attribute substring 10010 becomes 10110
- This operator was applied with probability .01
- DropCondition - performs more drastic generalization step by
replacing all bits for a particular attribute by a 1.
- in an attribute substring 10010 becomes 11111
- The operator was applied with probability .60
- the addition of these operators increased accuracy from 92.1% to 95.2% on a range of datasets
