If the model loads you should get a screen picture similar to the one above this text. Expand the OptStudy
branch in the operations tree, click Optimization once and then the Run button. The model starts cycling and
after a few rounds you will notice the saddle position changing, but not in a systematic grid like in the
parameters study. What you will see is gradual changes back and forth in different directions until the
changes wear off and the position converges. Every time you see the step counter below the Run button
changing number it is an indication that the optimizer has picked a new optimization direction to try. You
should see the number increasing in slow steps up to six before the process stops and the system
announces that it is finished. Please notice that the changes of saddle position in the last several steps is
very minute, which is typical for optimization: the first steps bring large changes and large improvements,
while the last many steps only improve slightly.
Now we are going to study the results in more detail using the AnyChart window. Do you still have the
AnyChart window from the previous lesson with the Metabolism parameter study open? It should look like
this:
If not, please run the ParamStudy again and plot the surface. When you have this surface ready, please
open another AnyChart window by clicking Window->AnyChart 2D/3D (new). In the new window, please
expand the tree down to Main.Bike2D.OptStudy.Output.Metab. Then click the Val variable under Metab. This
produces a simple 2-D graph showing the development of the metabolism over the 5 iterations:
