<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
 is better the smaller the value is you should return something like 
 (-1 * value) or (1 / value).</p>
 
 <p>Subclasses should use

 since usually the makro average (if available) should be optmized instead 
 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>
