Class LinearObjectiveFunction

java.lang.Object
org.apache.commons.math3.optimization.linear.LinearObjectiveFunction
All Implemented Interfaces:
Serializable
@Deprecated public class LinearObjectiveFunction extends Object implements 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.

Since:
