I wanted to know if there is any way of classifying the set of all non-linear multivariable functions. I wish to analyse something over all possible non linear functions with 4 variables. In fact these variables are binary variables. for example f(x,y,u,v)= x.y - u[itex]\oplus[/itex]v(adsbygoogle = window.adsbygoogle || []).push({});
