## Interface LeastSquaresOptimizer.Optimum

- All Superinterfaces:
    LeastSquaresProblem.Evaluation
  Enclosing interface:
    LeastSquaresOptimizer

      public static interface LeastSquaresOptimizer.Optimum
      extends LeastSquaresProblem.Evaluation

  The optimum found by the optimizer. This object contains the point, its value, and some metadata.

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `int` | `getEvaluations()` Get the number of times the model was evaluated in order to produce this optimum.
    `int` | `getIterations()` Get the number of times the algorithm iterated in order to produce this optimum.

- - ### Method Detail

    - #### getEvaluations

          int getEvaluations()

      Get the number of times the model was evaluated in order to produce this optimum.
      Returns:
        the number of model (objective) function evaluations

    - #### getIterations

          int getIterations()

      Get the number of times the algorithm iterated in order to produce this optimum. In general least squares it is common to have one `evaluation` per iterations.
      Returns:
        the number of iterations
