variations of traffic scenarios for coverage

given a basic scenario script and specifications as input.how can i create variations of scenarios using this basic scenario automatically? is there any way to do that? any machine learning or deep learning algorithm? any help would be appreciated..

Thanks in advance.cheers..

P.s- i know that i can vary the parameters of a function programmatically in automated driving toolbox.but i dont want to do this manually because i want to test my ECU with large number of scenarios and it will take lot of time everytime to vary the parameter manually.
