About the comparson between GA and policy gradient based method

Hi Brainxyz, I am a PHd candidate/visiting scholar now majoring in Music technology in Georgia Tech. Your project inspires me a lot. It is very interesting to investigate GA in DRL. But I am new in this field, could you please provide a code solving the Cartpole problem with policy gradient based method? I think it is valuable to see the difference between these two methods. Thank you very much!
