#partially-mapped-crossover

Question 1: Single choice

Partially mapped crossover (PMX) is applied to $P_1 = (2, 7, 8, 4, 6, 3, 1, 5)$ and $P_2 = (1, 4, 7, 8, 6, 2, 3, 5)$ with cut points after positions 3 and 6. The child keeps $P_2$ 's middle segment $(8, 6, 2)$ in positions 4–6 and takes the other positions from $P_1$ , resolving duplicates through the mapping between the two middle segments. Which child results?

(3, 7, 4, 8, 6, 2, 1, 5)1
(2, 7, 8, 8, 6, 2, 1, 5)2
(1, 8, 7, 4, 6, 3, 2, 5)3
(7, 4, 3, 8, 6, 2, 1, 5)4
