<DD><p>Returns the fitness depending on the value. The fitness values will be
 used for all optimization purposes (feature space transformations, parameter
 optimizations...) and must always be maximized. Hence, if your criterion

 of the mikro average. The mikro average should only be used in the (rare) 
 cases where no makro average is available but this is automatically done
 returned by <A HREF="../../../../com/rapidminer/tools/math/Averagable.html#getAverage()"><CODE>Averagable.getAverage()</CODE></A> in these cases.</p>
