goat 1.2 - an optimization solver component

We are happy to announce another update to the 1.x series of goat, an optimization solver component for Grasshopper. This release is the first to support the 64-bit versions of Rhino 5. As usual, this version is available for download at

http://www.rechenraum.com/goat/download.html

The main new features comprise:

Support for the 64-bit version of Rhino 5
New file organization to support parallel use from 32-bit Rhino 4 and 64-bit Rhino 5 installations

Please have a quick look at the new installation and update instructions at http://rechenraum.com/goat/documentation.html. In short, delete all old goat files from your Grasshopper's Components directory before copying the new files in.

Thanks to all who provided feedback to track down the 64-bit issue!

enjoy, simon

please give latest goat version 1.4 a try. I have not yet received any negative reports regarding gh 0.9.0014. If you encounter any problems with goat 1.4 and gh 0.9.0014, please let me know.

Hi,
I just updated to gh 0.9.0014 and I can't reproduce your problems. Could you please

verify that you have only one version of goat 1.4 installed (check Grasshoppers Components folders, both system-wide and user-specific, for files with "goat" in their filename)
and check that you installed goat according to the instructions in the following link (basically copy the entire contents of the goat archive to Grasshopper's User Components directory) http://www.rechenraum.com/goat/documentation.html#installation

If this does not help, please let me know your Rhino (4, 5 32bit, 5 64bit), Grasshopper and goat versions.

Thanks madmax for your message. Have you checked above two points ("only one installation of goat" and "correct installation of goat")? In particular, please make sure that in your Grasshopper's User Components directory, there are

two files called "goat_main.gha" and "goat_includes.gha"
and two directories called "goat_32bit" and "goat_64bit", each storing a single file called "goat_nlopt.dll"

Please let me know your findings, best

hi,
your first sentence makes me wonder whether you installed goat correctly (please note that installation instructions changed). Please check and confirm, that you simply copied the entire contents of the goat installation archive over to Grasshopper's User Component directory. As a result, you should have two files ("goat_main.gha", "goat_includes.gha") and two directories ("goat_32bit", "goat_64bit") there.

If you have three goat related files only, you did not install goat correctly. "goat_nlopt.dll" must be located in the "goat_32bit" and "goat_64bit" directories.

No matter what the cause is, I assume that is a problem with goat that we will fix soon, so no Windows update will be necessary.

best, simon
