Обсуждение: Improving GEQO
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?
Regards.
