[SQ4 B9] Please add this effective duplicate filter for the genetic evolution

An effective duplicate filter to filter out identical strategies would be needed for the genetic evolution. As you can see, the genetic evolution fills up the databank with the exact same strategy over and over. I would highly suggest that you filter out such strategies directly from within the population of the current generation and replace them with new ones. That is how the other trading system builder that I am using does it.

1) At the end of each generation, the whole population is checked for duplicate members.
2) If a duplicate member is found, it is replaced by a completely new randomly generated member (strategy in our case).
3) The evolution continues with a de-duplicated population into the next new generation.
4) This duplicate check/replacement is repeated at the end of EACH generation.


This way we can avoid such scenarios easily and it also inserts some completely "fresh blood" into each generation in case it begins to create many duplicates (which is a sign of stagnation too).
