GENERATED FROM PYTHON SOURCE LINES 67-74 Create and execute scenario --------------------------- The next step is to build a MDO scenario in order to maximize the range, encoded 'y_4', with respect to the design parameters, while satisfying the inequality constraints 'g_1', 'g_2' and 'g_3'. We can use the MDF formulation, the SLSQP optimization algorithm and a maximum number of iterations equal to 100. ..

GENERATED FROM PYTHON SOURCE LINES 87-93 Post-process scenario --------------------- Lastly, we post-process the scenario by means of the :class:`.BasicHistory` plot which plots any of the constraint or objective functions w.r.t. optimization iterations or sampling snapshots. This method requires the list of variable names to plot. ..
