I am currently working on a PSO which works fine and returns the cost function (which has different variables) with the lowest error rate just as expected.

Now here is my question:

Is there a way to calculate the importance of the variables of the cost function in regard to the error rate?

I want to know which variables have the biggest impact and/or if some variables have some dependencies. I know this is very similar to feature selection but i dont have a class space.
