Hello all,

I've recently begun learning how to use ecj. I can competently use GP, 
and now I'm playing with some GA's. I'm having an issue with my GA's 
parameters. I assume it is something simple (like I have got the base 
wrong or something).

I want some of my genes to be of different lengths, for 
IntegerVectorSpecies the class documentation says I can use 
base.min-gene.n for this purpose. I'm doing this but my genes are not 
getting their specific limit, only the overall limit.

I'm going to include my params file, its pretty small and straight 
forward. My gene 5 had a value 94 last run when its limit is 20.

Thanks in advance!
Brad
