   I am working on a simple GA in order to create a simple melody and I   
   now facing the problem of the fitness assignment. I have been searching   
   the groups but noboody seems to give a clear answer. Supposing that the   
   problem is well defined and you know what is a "good melody" and what   
   is a "bad melody" how will the fitness assignment take place? For   
   instance, let's take the chromosomes:   
      
   1 2 3 2 2 5 6 7 2   
   2 2 2 3 3 2 1 4 6   
   2 1 4 2 6 3 5 4 7  (the numbers represent notes)   
      
   If good melodies are the "5 6 7" and "3 3" what fitness will I have to   
   give  to the corresponding chromosomes in order to make them survive   
   through evolution? If I give them just a true-false fitness,   
      
   1 2 3 2 2 5 6 7 2 true   
   2 2 2 3 3 2 1 4 6 true   
   2 1 4 2 6 3 5 4 7 false   
      
   then the motif "3 3" will appear more often because it has smaller   
   length.Is there an equation that gives the rate of surviving according   
   to the length?Goldberg's investigation is only for binary   
   representation where many things are completely different.   
      
   Thanks!
