Hello Robert Vierequal%20size2.gh

I use an octopus version 0.4 on Rhino version 13 in my project. When I use different One-objective and two-objective function three or four times and run the octopus, its speed slows down a lot. I used it with Rhino versions higher than 7, but it slows down again after 4 times clicking on octopus. Someone can solve my problem. The speed of octopus all versions is also very slow. Please help me. My goal is to reach equal sides of triangles. Is it a bug or Rhino or octopus or algorithm in grasshopper? Please help me. Thanks

Hi Robert. Can you help me with this simple example.I was able to get the longest line between the two lines with the Galapagos but with Octopus I could only get the shortest line.How do I find the longest line between two other lines with Octopus?thaky you very much

Hi Robert,

I notice an very interesting function of Octopus that considers the users' preferences. This is useful in architectural form optimization problem. I'm now into the study with regard to the integration of preference into optimization algorithm. Could you give me any information about your approach in Octopus? I think your help will be important in my future study. Maybe I could use OctopusE to implement my approach if I have some advances. 

Looking forward to your response. Thanks a lot.

Best regards,

Dan

Hello Robert any Chance you can help me with this issue

The Octopus collapses over this error :

Error in SPEA2 archive building when finding m_dist: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

at System.Collections.Generic.List`1.get_Item(Int32 index)

Error: Index was out of range. Must be non-negative and less than the size of the collection.

I assigned 30 for population and 8 for generation 

It usually collapses afetr finishing the first 30 population and when it starts the external 30 it collapses 

I tried the whole process on similar case and it succeeded :/ , that is driving me crazy 

Thanks in advance 

Hello Robert,

Can you please take a look at this problem I am having with space truss.

For some reason I am only getting null members, not compressional and tensional too.

I posted files too.

Thank you.
