|---|
| 51 | .nf |

| 54 | Example: |
|---|
| 55 | Change any string in PGA_NEWPOP that is an exact copy of a string |
|---|
| 56 | in PGA_OLDPOP. |
|---|
| 57 | |
|---|

|---|
| 64 | PGAChange(ctx, b, PGA_NEWPOP); |
|---|
| 65 | |
|---|
| 66 | |
|---|
| 67 | Check if the best string in population PGA_OLDPOP is a duplicate of any |
|---|
| 68 | of the strings in the first half of population PGA_NEWPOP. |
