Attractor Points and Galapagos to Optimize Sunshade Openings

Dear forum,

I am trying to create a tool which is supposed to create a sunshade in front of a facade. The sunshade has individual opening sizes and to get the best result (radiation analysis of window in facade) I am using attractor points to define these sizes. Now to reduce the amount of time it takes (every calculation includes one radiation analysis) I am trying to find an effective way of defining the sun shade openings while using as little sliders as possible for galapagos.

Started with 1 point (x,y,z slider), now thinking about Point Population with 5 points he can pick. Has anyone experience on this or references?

Attached an image which hopefully clears it up a bit. Many thanks already!
