  - ### Method Detail

    - #### getSolution

          public PointValuePair getSolution()

      Retrieve the best solution found so far.

      Note: the returned solution may not be optimal, e.g. in case the optimizer did reach the iteration limits.

      Returns:
        the best solution found so far by the optimizer, or `null` if no feasible solution could be found

    - #### isSolutionOptimal

          public boolean isSolutionOptimal()

      Returns if the found solution is optimal.
      Returns:
        `true` if the solution is optimal, `false` otherwise
