It's not overfitting because if you had 1000^5 possibilities the only way to solve a 5 dimensional problem like this is to find ranges by narrowing them down with one final exhaustive study, and that is how real financial research in the fields of artifical intelligence is done.

Judging by your phrasing of the question, you mean the latter. The ranges start at 1 to 1000, so 1000^5 is how many possibilities the genetic algorithms must sort through to find the best ranges. 10^15 is the same value as 1000^5. Edit/Delete • Quote • Complain
