The selected vectors undergo a recombination process to produce offspring vectors x ′ , y ′ . Specifically, a cut point is randomly selected to split each of x, y into two segments: (x 1 , x 2 ), (y 1 , y 2 ). Then, x 1 is combined with y 2 , and y 1 is combined with x 2 to produce the offspring vectors x ′ and y ′ .
