  abstract =     "Implicit fitness sharing is an approach to the
                 stimulation of speciation in evolutionary computation
                 for problems where the fitness of an individual is
                 determined as its success rate over a number trials
                 against a collection of succeed/fail tests. By fixing
                 the reward available for each test, individuals
                 succeeding in a particular test are caused to depress
                 the size of one another's fitness gain and hence
                 implicitly co-operate with those succeeding in other
                 tests. An important class of problems of this form is
                 that of attribute-value learning of classifiers. Here,
                 it is recognised that the combination of diverse
                 classifiers has the potential to enhance performance in
                 comparison with the use of the best obtainable
                 individual classifiers. However, proposed prescriptive
                 measures of the diversity required have inherent
                 limitations from which we would expect the diversity
                 emergent from the self-organisation of speciating
                 evolutionary simulation to be free. The approach was
                 tested on a number of the popularly used real-world
                 data sets and produced encouraging results in terms of
                 accuracy and stability.",
