English (East Yorkshire): perhaps from an unattested Middle English personal name Asy, Acy. This would be from late Old English si, ultimately a shortened form of Old English thelsige, or from the Old Norse personal name si, found as Ase in Lincolnshire (12th century).

Acey is a name that has gained popularity recently as a unisex name that can be given to both boys and girls.

The roulette wheel selection method is used for selecting all the individuals for the next generation. It is a popular selection method used in a genetic algorithm. A roulette wheel is constructed from the relative fitness (ratio of individual fitness and total fitness) of each individual.

To determine the winning number, a croupier spins a wheel in one direction, then spins a ball in the opposite direction around a tilted circular track running around the outer edge of the wheel.
