generative modeling for Rhino
Octopus is seen as an extension to Galapagos by introducing 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 uniformly.
Results are shown in a two- to five-dimensional, 3D-navigable solution-viewport.
User-preferences on specific solutions can be specified when the optimization is paused, so the further optimization gets densfied around the selection. The history of the evolutionary runs can be recorded, saved, and loaded again.

Some examples and a videa to get started are provided here.
For now bases on the Improved Strength Pareto Evolutionary Algorithm SPEA-2 by Zitzler, Deb, Thiele at ETH Zürich and David Rutten's Galapagos User Interface. It is developed by Robert Vierlinger in cooperation with Christoph Zimmel, karamba3d.com and Bollinger Grohmann Schneider ZT GmbH Vienna.
Hi:first Great Job.................I´m testing the octopus, 62 genes, 3 objetives, and max. generations=0 (endless)as i set the max generations in 0, the octopus will continue until finding the best…Continue

Hi Rob,So since you brought it up, is it possible to add the preference factor from an external text file for example?In general as a wish it would be great if to add an option to modify objectives…Continue

Hi Rob,Would you please give me a brief explanation on the settings.I would like to record my screen as I am running the optimization using octopus, but the result of each iteration comes as goes in…Continue
