We follow your
advice, our goal is improve the quality of the solution and we made it,
however the total query execution time is higher.
Regards.

Hello, my partner and me are working with the goal of improve the GEQO's
performance, we tried with Ant Colony Optimization, but it does not
improve, actually we are trying with a new variant of Genetic Algorithm,
specifically Micro-GA. This algorithm finds a better solution than GEQO
in less time, however the total query execution time is higher. The
fitness is calculated by geqo_eval function. Does anybody know why this
happens?
Well, for one thing, you can't just do this:
+ aux = aux1;
without totally confusing all your subsequent steps.
You'd want to copy the pointed-to data, likely, not the pointer.
