Multi-objective optimization but the function equation is unknown?

Firstly, I am totally out of my expertise zone so please bear with me.

I developed a fluid dynamic engine with 5 exposed parameters (say A,B,C,D,E). When you give this engine these 5 parameters, it does magic and give out a value 'Z'.

I want to write a script which can explore which combinations of A-E give lowest (or close to lowest) value of Z.

I know optimization algorithm exists, but from all of my search for examples, they use some function.

So I guess my function would simply be minimize Z? But where do A-E go?
