Thanks for your advice. I have tried both suggestions.
1. float test = ga.statistic().bestIndividual().score(); - this gives me the score of the best individual but not the value. This works.
2. ga.statistics().bestIndividual().gene(0) - throws the following error:
control0406.cpp:537: error: ˜const class GAGenome" has no member named ˜gene"
As far as I understood it the GAStatistics class a member function named bestIndividual which is declared in this way:
const GAGenome& bestIndividual(unsigned int n=0) const
which further refers to the class GAGenome which has no member named "gene" - hence the error
Maybe I've missed something.
If you have other suggestions please let me know.
Thank you for your effort,
