  protected GoalType getGoalType()

  Deprecated. 

  Returns:

  the optimization type.

• getFunction

• setMaxIterations

  public void setMaxIterations(int maxIterations)

  Deprecated. 
  Set the maximal number of iterations of the algorithm.

  Specified by:

  setMaxIterations in interface LinearOptimizer

  Parameters:

  maxIterations - maximal number of function calls

• getMaxIterations

  public int getMaxIterations()

  Deprecated. 
  Get the maximal number of iterations of the algorithm.

  Specified by:

  getMaxIterations in interface LinearOptimizer

  protected void incrementIterationsCounter()
                                     throws MaxCountExceededException

  Deprecated. 
  Increment the iterations counter by 1.

  Throws:

  MaxCountExceededException - if the maximal number of iterations is exceeded

• optimize

  public PointValuePair optimize(LinearObjectiveFunction f,
                        Collection<LinearConstraint> constraints,
                        GoalType goalType,

                          throws MathIllegalStateException

  Deprecated. 
  Optimizes an objective function.

  Specified by:

  optimize in interface LinearOptimizer

  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

• doOptimize

  protected abstract PointValuePair doOptimize()
                                        throws MathIllegalStateException

  Deprecated.
