@Deprecated
public class LinearObjectiveFunction
extends java.lang.Object
implements java.io.Serializable

An objective function for a linear optimization problem.

A linear objective function has one the form:

 c1x1 + ... cnxn + d
 

The c_i and d are the coefficients of the equation, the x_i are the coordinates of the current point.

Since:
