  micro average from both (or more) criteria. This is usually achieved by
  correctly implementing <A HREF="../../../../com/rapidminer/tools/math/Averagable.html#buildSingleAverage(com.rapidminer.tools.math.Averagable)"><CODE>Averagable.buildSingleAverage(Averagable)</CODE></A>.

<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>

 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>

<DD>This method should build the average of this and another averagable of
 the same type. The next invocation of <A HREF="../../../../com/rapidminer/tools/math/Averagable.html#getMikroAverage()"><CODE>Averagable.getMikroAverage()</CODE></A> should return the
 average of this and the given averagable. Hence, this method is used to build
 the actual micro average value of two criteria. Please refer to

 implementation example.
