algorithmic modeling for Rhino
Octopus is a plug-in for applying evolutionary principles to parametric design and problem solving. It allows the search for many goals at once, producing a range of optimized trade-off solutions between the extremes of each goal.
Also see octopus.E for custom evolutionary algorithms.

It is part of a range of tools developed at the University of Applied Arts Vienna, and Bollinger+Grohmann Engineers.
Octopus introduces multiple fitness values to the optimization. The best trade-offs between those objectives are searched, producing a set of possible optimum solutions that ideally reach from one extreme trade-off to the other.
Based on SPEA-2 and HypE from ETH Zürich and David Rutten's Galapagos User Interface. Developed by Robert Vierlinger in cooperation with Christoph Zimmel, karamba3d.com and Bollinger+Grohmann Engineers.

Does the latest version of Octopus work with Grasshopper 0.9.0076.... download page says it is compatible with 0.9.0075.
If only works with 0.9.0075 any tips on where to find thta version of Grasshopper?
Thanks.
What is the algorithm to calculate hypervolume metric? Is it HSO?
Can Octopus pick the best solution itself? Where?
How does Octopus deal with multicriteria weighting and multicriteria scores?
Haha no prob. You should keep the Awesome tab for the next release. Thanks for all your work in this area.
Oh this is a mistake in compiling the plug-in, this component was purely for development, and not supposed to be in the official release.
Sorry for the confusion,
Best
Robert
Is there any version of Octopus that works with Grasshopper 0.9.0064? I can load the component, but it crashes whenever I delete it from the canvas.
Hello Abraham,
the files are unblocked. I can use the Octopus component and upon opening the example files I can see the results of the default calculation. But when I click Start again the log file 01_singleObjective_Diversification_OctopusErrorLog_20131119.txt says:
Error, reduction of environmental selection did not yield the correct archive size
I have previously used Octopus 0.1 flawlessly.
You need to unblock the .dll file.
