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
