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)
at GH_GA.GA.BuildSPEA2Archive(Genome[] oldInds, List`1& nonFront, List`1& front)

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

StackTrace: at System.Collections.Generic.List`1.get_Item(Int32 index)
at GH_GA.GA.BuildSPEA2Archive(Genome[] oldInds, List`1& nonFront, List`1& front)

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.

Hey Robert!

Nice to see you here. We have an interesting project with Andrew in which I want to try some structural optimization. 

Thanks for the link, I'd check it in the morning.

 

Cheers,

Itai.
