public class LinearObjectiveFunction
extends java.lang.Object
implements java.io.Serializable
    Deprecated.
    As of 3.1 (to be removed in 4.0).
    An objective function for a linear optimization problem.

    A linear objective function has one the form: 

     c1x1 + ... cnxn + d
    The ci and d are the coefficients of the equation, the xi are the coordinates of the current point.
