    Depending on the choice of ``speculative`` option in ``optimization`` section, the calculations for current best solution and for the gradient might be split in multiple batches, see `Everest documentation <https://everest.readthedocs.io/en/latest/config_reference.html#>`_.
 
-The :ref:`figure_objectives_ws` shows average objective function at the iterations of the optimization experiment (average NPV over all geological realizations). The increase in objective function value of $7.16e+08 was achieved by  selecting 5 wells and placing them in an optimal order (see :ref:`_figure_controls_wellnumber_ws` and :ref:`figure_controls_priorities_ws`).
