We really often fill the entire population with the same individual copyed again and again. This is totally useless and waste space and computation time.
We have to remove them !
When we tested the algorithm on the 10^x function with points from 0 to 10 we got the perfect match after simplification of the population while the fitness was still near 0%.
This is caused by float approximation with huge values.
Could we find ideas to fix that ?

Often when you test the program with the standard depth, it does not converge toward a solution because the population quickly get too much complex before having an approximate solution.
How could we solve that ?
When we call Stats.genetic_diversity with apparently good arguments (see in genetipe.ml) we just end up with :
Fatal error: exception Invalid_argument("index out of bounds")
Currently we have a fixed range for the choice of the constants. Maybe it would be a good idea to compute that range from the points.
