Topology in pagmo2 about pagmo2 HOT 7 CLOSED

It is indeed the next thing we are going to work on. But you will have to wait some weeks unfortunately.

Currently we are busy packaging ....

Thanks for the reply! Looking forward to it.

#102 is addressing this request.

Update on the topology/migration feature? It's been a year...

Also, how important is island migration in terms of optimization quality? Do archipelagos without migration result in significantly worse solutions?

from pagmo2.

The topology/migration feature is under development. The reason it is taking so long is to be found in our development model that tends to favour small incremental changes over big ones.

As to your question on how much it counts for the optimization quality, my experience is that it does quite a lot, you can read about it on our paper "generalized island model" on the section called " migrate or not migrate"

I see. If I want island migration, what options do I have in terms of a Python optimization library? Would I have to use PyGMO 1? Are there any other similarly advanced Python libraries that support island migration (other than the first version of PyGMO)?

from pagmo2.

Migration is now available in pagmo 2.11, released today.

Note that not all topologies have been ported from pagmo 1 (we have at the moment the unconnected, ring and fully_connected topologies). We will gradually add the missing topologies in the next few weeks.
