Optimization depends on the initial values that you select. I have some suggestions for AWR. At the beginning, you should not set for high resolution.
1) Limit your upper and lower values of the components.
2) Do not use high resolution (for example 0.001pF)
3) Prefer higher or lower (< or >), not equal (=)
4) If optimization is not going well at the first 5 minutes, probably your optimization technique is not proper. change it and try again
5) do not optimize more than 5 components at the same time
