Optimization Plug-In for Grasshopper: How to use Galapagos' interface and gene pool?

Finally it works! Thanks a million times!

The bit I missed was basically avoiding SolveInstance() to run again, with this:

        if (_form != null)
            return;

or in my case, instead of a form, just a class instance

        if (opti != null)
            return;

Thomas, I owe you many glasses of beer! :smiley:

Hi all,

Trying to use Thomasā€™ custom C# component in Rhino 6, GH build 1.0.0007, and am getting this error:

ā€œ1. Error (CS1703): An assembly with the same identity ā€˜Microsoft.CSharp, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3aā€™ has already been imported. Try removing one of the duplicate references.ā€

I tried commenting out ā€œusing Microsoft.CSharp.RuntimeBinderā€, no luck.

Does anyone see any issues running this code in GH for Rhino6? Or, are there new solutions for accessing the gene pool component within a custom C# component?

Hi Scott,

Have a look at this GitHub repository, which provides a shell for optimization in Grasshopper, including support for genepools. The code for genepools is in Grasshopper_InOut.cs.

I havenā€™t looked at it in a while. but for all I know it should still work.
(I had a look at the component I posted here, but I have no idea why it isnā€™t working anymore.)

Cheers,
Thomas

Hi Thomas,

Iā€™m a PhD student working on evolutionary architecture, and Iā€™m interested in writing a galapagos-like component, with a novel solver. I have your FrOG repo which looks very promising, but it references the GalapagosLibrary.dll. I assume this was relevant in Rhino 5, but I now have Rhino 8, and I canā€™t find the .dll Do you know where to find it?

Thank you very much,
Paul Kalnitz
