What forms of interaction do Random Forests take into account? I understand from other posts ( Including Interaction Terms in Random Forest ) that Random Forests take into account interactions like x1 * x2, but what about x1 - x2, x1 / x2 and other more complex forms of interactions?

What are other algorithms that take into account complex interactions between predictors?

*I have probably used the term "interaction" too loosely, to include all forms of operations or functions that uses multiple variables. If there is a technically correct term for this, please correct me.
