| 6 | # The following is an example of Inter-subpopulation exchange |
|---|
| 7 | # within the same process, using three subpopulations, |
|---|
| 8 | # with the GP Ant example. In the example below, we've set |
|---|
| 9 | # up three subpopulations, and the exchange is as follows: |
|---|
| 10 | # subpop 0 sends inds to subpops 1 and 2, subpop 1 sends |
|---|
| 11 | # inds to subpop 2, and subpop 2 sends inds to subpop 0. |
|---|
| 12 | # All three subpops start exchanging immediately (after |
|---|
| 13 | # population initialization) and thereafter send every two |
|---|
| 14 | # generations. They exchange 3 individuals each. |
|---|
| 15 | # |
|---|
| 16 | # If you're looking instead for multi-process, network island |
|---|
| 17 | # models, see the 3-Island and 8-Island examples |
