How to optimize the output

Hi everyone.

I got some trouble in my work. As a target, I’d like to minimize the number of vectors, but I failed to do it by galapagos. I try to add a number below 3 to each XYZ component to reduce the vectors’ number.In fact, there are 3 different vectors at least by manul optimization, and galapagos only reach 8 different vectors.Is there anything going wrong?
