I am trying to optimize the arrangement of bars in a steel truss structure, manipulating the direction of the diagonals and de-/activating the verticals with sliders (contained in the gene pools), see picture below.
My objective is minimum weight with a penalty for high displacements.
Later on, if it works, I would like to add more variables.
It seems that Galapagos only finds solutions that are worse than the one I find manually. How do I help the algorithm with finding the right solution? Is it the right approach for topology optimization? Why does it matter what solution is start with?
Additional question: How is Karamba considering buckling and where can I find the buckling lengths?
