Grasshopper

algorithmic modeling for Rhino

Hi

I have just downloaded and installed Octopus... Great to have a Pareto multi-objective optimisation add-on! Nice job! Really exciting!

I couldn't get it to work though... it crashes Rhino when I press 'start'.

I have made sure I have the latest service release of Rhino 5 (24/5/13), and latest GH  (9.0056).

I have also have this error message in Octopus (However I am not using any Gene Pool Component):

GalapagosComponents.gha was not found, so GenePools cannot be used with Octopus.

Galapagos is installed and works... do the gha file need to be located in a particular location for Octopus to find it?

Thanks for your help.

Thanks Robert!

I installed it and I have two simple question!

- What about the new P and PS?

- How can I record/save the history?

- I'm sorry, what do you mean by P and PS?

- There are two fields on the right side of the viewport, specifying the intervals (in generations) in which

   1) at one hand the history is recorded (which then is saved to your grasshopper definition) and

   2) on the other hand the file is saved under an incremental filename, in case the process crashes (so you dont loose your run's results)

aside of that, you can just run octopus, and after you stopped it you save your grasshopper definition. all data including the current state and the history is saved to your GH file. i tried to keep the data small, but in case you get files with sizes of 1GB and greater, you should increase the 'record history interval' to something like 100 ..!

exporting the raw numbers is not possible in the current release. if you need it i can implement it for the next one, or just slightly update the current release.

best

Robert

I'm sorry: the first question was about the input/output P and Ps

Is there a legend that explane the meaning of the color, the dimensio and the position of "box result" in the result visualization?

How can I decide what "Mutation Rate" of my optimization? I tried to change the 0.05 default value and the optimization crashed and a red message suggested me to reset the option!
