Claim 5:
6. The face recognition method according to claim 5, wherein a method of selecting the N parents according to the result of the first fitness evaluation in step S2 comprises:
C1: setting a first threshold α and a second threshold β;
C2: randomly selecting two trained first individuals from a trained initial population, and determining whether a difference between accuracy rates of the two trained first individuals is greater than α, when the difference between the accuracy rates of the two trained first individuals is greater than α, selecting a trained first individual with a relatively large accuracy rate of the two trained first individuals as a parent of the N parents; when the difference between the accuracy rates of the two trained first individuals is equal to or smaller than α, turning to step C3;
C3: determining whether a difference between complexities of the two trained first individuals is less than β, when the difference between the complexities of the two trained first individuals is less than β, selecting a trained first individual with a relatively large accuracy rate of the two trained first individuals as the parent; when the difference between the complexities of the two trained first individuals is equal to or greater than β, selecting a trained first individual with a relatively small complexity of the two trained first individuals as the parent; and
C4: selecting the N parents according to step C2 to step C3.
