Optimization of Passive suspension parameters using Genetic Algorithm

May you please support me through an example:

I want to optimize Passive suspension parameters i.e. spring and damping values to obtain minimum sprung mass acceleration or minimum sprung mass rms accelration values. How to do this using Genetic Algorithm. I am having Simulink model of the system. I have tried a lot but could not find such an example having m code and method for doing so. I will be highly thankful to you if such support is provided.

Thanks in advance. with Warm Regards Devdutt
