Wish: Import/modify the preference from a list

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 using an external file, or some other way that could be done by scripting not selecting from the interface, before GA start the evaluation for each generation.

Best,

Hey Mostapha,

can't you just read your file from grasshopper every time a new solution is triggered for octopus?

Hey Rob,

The problem is that I have a delay in collecting the extra objective so I cannot add it to the process at the same time that Octopus collects the objectives.

The graph below shows the workflow that I'm currently working on using MATLAB. As you can see in the left bottom corner there is a review by the designer(s). I'm adding this evaluation as an extra objective function for each individual. What I do now is to consider a dumb extra objective function that I overwrite before the evaluation process for each generation. I was thinking to apply the same process using Octopus.

Moreover, the option to overwrite/modify the objectives will allow the user to use cloud computing in a similar manner. Assign dumb objective functions for all the generation, extract the individuals, run the real calculations on the cloud, collect the objectives, overwrite the dumb objectives with the real ones and then let the Octopus does the evaluation, and produce the next generation.

I don't know the details of how Octopus collects the data so it might be already possible in some way that I'm not aware of.

Best,

Mostapha
