LinearObjectiveFunction (Apache Commons Math 3.6.1 API)

java.lang.Object
- org.apache.commons.math3.optim.linear.LinearObjectiveFunction

All Implemented Interfaces:

Serializable, MultivariateFunction, OptimizationData
```
public class LinearObjectiveFunction
extends Object
implements MultivariateFunction, OptimizationData, Serializable
```
An objective function for a linear optimization problem.
A linear objective function has one the form:
```
 c₁x₁ + ... c_nx_n + d
 
```
The c_i and d are the coefficients of the equation, the x_i are the coordinates of the current point.
Since:

2.0
