[Quantproject-developers] QuantProject/b1_ADT/Optimizing/Genetic Genome.cs, 1.19, 1.20

[Marco M. <mi...@us...>]

Update of /cvsroot/quantproject/QuantProject/b1_ADT/Optimizing/Genetic
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv9981/b1_ADT/Optimizing/Genetic

Modified Files:
	Genome.cs 
Log Message:
Fixed very critical bug !!!
After changing Fitness and Meaning property access, I forgot to reset the
private fields when single genes are changed, in order to force a new 
fitness and meaning calculation. These kinds of error should be avoided through
a more object oriented organization of the GeneticOptimizer, but I think
that would slow down scripts' execution.
Now the GeneticOptimizer has turned to work properly
