We consider a minimization problem over the interval :math:`[0,1]`
of the :math:`f(x)=x^2` objective function:

.. GENERATED FROM PYTHON SOURCE LINES 36-43

.. code-block:: Python

    discipline = create_discipline("AnalyticDiscipline", expressions={"y": "x**2"})

    design_space = create_design_space()
    design_space.add_variable("x", l_b=0.0, u_b=1.0)

    scenario = create_scenario([discipline], "DisciplinaryOpt", "y", design_space)


.. GENERATED FROM PYTHON SOURCE LINES 44-45

We solve this optimization problem with the gradient-free algorithm COBYLA:

.. GENERATED FROM PYTHON SOURCE LINES 45-47

.. code-block:: Python

    scenario.execute({"algo": "NLOPT_COBYLA", "max_iter": 10})


.. GENERATED FROM PYTHON SOURCE LINES 48-50

Then,
we save the results to an HDF5 file for future post-processing:

.. GENERATED FROM PYTHON SOURCE LINES 50-52

.. code-block:: Python

    scenario.save_optimization_history("my_results.hdf")


.. GENERATED FROM PYTHON SOURCE LINES 53-54
