# Optimization result does not show convergence

Hi,

I have tried to use different optimization plugins in grasshopper to optimize a simple room with lamella shading regarding the daylighting level and glare, thus UDI and DGP value.

The climate is set in Denmark, and the variances are the rotations, the numbers and the size of the shading panels.

However, using both Galapagos and Opossum, my result did not show any convergence.

This is the optimization result of DGP from Galapagos.

This is the optimization result of UDI from Galapagos.

This is the optimization result of UDI from Opossum.

Could it because of the climate? Does anyone have any suggestions?

I appreciate your time and help

Thank you.

Based on the MD-graph (the middle square one) you only have three sliders with only 7, 5 and 4 unique states each. That means there are only 7 \cdot 5 \cdot 4 = 140 possible states for this room to be in. This has basically turned into a Brute Force search. So since every possible combination has been tried, you’re guaranteed to have found the best one.
