2.8 Scheduler (Optimizer)

Before the system is ready to start the execution of the analysis, you have to choose a scheduler that will run the optimization process.
The Scheduler component has been introduced in the Work Flow desktop in section 2.4.
Enter the Scheduler Properties window double clicking its icon, as usual: here you can select the scheduler (optimizer) that best fits your needs.
The list on the left shows all available optimizers, select one and its parameters will show in the right window (see Fig. T2.8.1).
You can change the optimizer parameters, when you have finished click the Apply Scheduler button.
To reset all changes made to the parameters, click the Default Parameters button.

For this tutorial we select MOGA, a multi objective optimizer (see Fig. T2.8.1), with 32 generations (so the scheduler will perform 32 x 10 analysis, since 10 was the size of the DOE): so the Number of Generations field value has been set to 32.
Except MOSA, FMOGA, and MMES all the other optimisers are single objective, and therefore modifications to the objectives definitions should be made to allow the use of e.g. SIMPLEX or BFGS.

Fig. T2.8.1: MOGA optimizer properties.

Note: in our case, the Random Generator Seed has been set to 1 for repeatability's sake: in this way, if you want, you can reproduce exactly the results we present in these pages. Any value of the seed >0 determines univocally the stream of pseudorandom numbers that are generated. A value equals to 0 means that the sequence is automatically seeded to a value based on the machine clock.

At this point the logic of the project is completed: all the components have been defined. At last the Logic Log shows no error, as can be seen in Fig. T2.8.2.

Fig. T2.8.2: the Work Flow window: now the logic is completed.
