# xpress.nonlin

Purpose

Internal class representing functions which are neither quadratic nor linear nor constant. It can be used and combined to create constraints and objective function of an optimization problem. The user cannot explicitly create an object of this class.

Example
The following creates a nonlinear expression and sets it as the objective function of a problem:

    import xpress as xp

    p = xp.problem()

    x = p.addVariable()

    obj = x**4 + xp.exp(x)

    p.setObjective(obj)
