LinearOptimizer (Apache Commons Math 3.3 API)

All Known Implementing Classes:

AbstractLinearOptimizer, SimplexSolver

Deprecated.
As of 3.1 (to be removed in 4.0).
```
@Deprecated
public interface LinearOptimizer
```
This interface represents an optimization algorithm for linear problems.
Optimization algorithms find the input point set that either maximize or minimize an objective function. In the linear case the form of the function is restricted to
```
 c₁x₁ + ... c_nx_n = v
 
```
and there may be linear constraints too, of one of the forms:
- c₁x₁ + ... c_nx_n = v
- c₁x₁ + ... c_nx_n <= v
- c₁x₁ + ... c_nx_n >= v
- l₁x₁ + ... l_nx_n + l_cst = r₁x₁ + ... r_nx_n + r_cst
- l₁x₁ + ... l_nx_n + l_cst <= r₁x₁ + ... r_nx_n + r_cst
- l₁x₁ + ... l_nx_n + l_cst >= r₁x₁ + ... r_nx_n + r_cst
where the c_i, l_i or r_i are the coefficients of the constraints, the x_i are the coordinates of the current point and v is the value of the constraint.
Since:

2.0

```
void setMaxIterations(int maxIterations)
```
    Deprecated.
    
    Set the maximal number of iterations of the algorithm.
    
    Parameters:
    maxIterations - maximal number of function calls
  - getMaxIterations
```
int getMaxIterations()
```
    Deprecated.
    
    Get the maximal number of iterations of the algorithm.
    
    Returns:
    maximal number of iterations

```
int getIterations()
```
    Deprecated.
    
    Get the number of iterations realized by the algorithm.
    The number of evaluations corresponds to the last call to the optimize method. It is 0 if the method has not been called yet.
    
    Returns:
    number of iterations

```
    Deprecated.
    
    Optimizes an objective function.
    
    Parameters:
    f - linear objective function
    constraints - linear constraints
    goalType - type of optimization goal: either GoalType.MAXIMIZE or GoalType.MINIMIZE
    restrictToNonNegative - whether to restrict the variables to non-negative values
    
    Returns:
    point/value pair giving the optimal value for objective function
    
    Throws:
    
    MathIllegalStateException - if no solution fulfilling the constraints can be found in the allowed number of iterations
