After the pin replacement, if the smallest intersection total number (β) is β ≠ 0, the intersection total number (β) is compared with the reference intersection total number (α). To do. When there are two or more (β), β that minimizes the sum of pin pairs is adopted.

  When the process of step S2810 is completed, the process proceeds to the process of step S2812, and after the comparison, if α> β, the connection state of the total number of intersections (β) is adopted, the reference is changed, and the process returns to step S2806. Repeat the process.

  When the process of step S2812 is completed, the process proceeds to step S2814. After the comparison, when α ≦ β, the connection state of the total number of intersections (α) is adopted, and the process within the same group is ended. If there is another group, the process returns to step S2804 to repeat the process, and if there is no other group, the process ends.
