Claim One:
1. A computer implemented data mining system, for use with a data mining training database identifying samples of testing data, each of the samples containing a plurality of data items, comprising: a memory storing a candidate database having a pool of candidate individuals, each candidate individual having a plurality of conditions and outputting, for each of a plurality of the data items in a sample, an action which depends upon application of the individual's conditions to the data item, the conditions including a state of the individual, and the actions including at least one which affects the state of the individual if asserted, each candidate individual further having associated therewith an indication of a respective fitness estimate; a candidate pool processor which: tests individuals from the candidate pool on the testing data, and updates the fitness estimate associated with the individuals being tested in dependence upon actions asserted by the individuals in the testing; and a harvesting module providing for deployment of selected ones of the individuals from the candidate pool, wherein testing individuals from the candidate pool on the testing data includes, for each individual tested: applying the conditions of the individual to data items of the samples to assert actions; and for a subset of at least one but less than all of the data items to which the conditions are applied, modifying the asserted action for the data items in the subset.
