Searching for a Maximum Value

You can use the Maximization Optimization type. In this example, the algorithm searches for the parameter values corresponding to a maximum value for Function2. The Simulated Annealing method is used. Lower and upper bounds (-10 and +10) are specified for the x argument.

  1. Create a Representation and add the parameters and formulas shown below.
  2. From the Compass, click 3D Modeling Apps and select Product Engineering Optimizer.
  3. Click Optimization .
  4. Define the data required to run the optimization algorithm as follows:

    Optimization Type

    		Maximization

    Optimized Parameter

    		Function2

    Free Parameters

    		x - Inf. Range: -10 ; Sup. Range: +10

    Algorithm

    		Simulated Annealing Algorithm

    Convergence speed

    		Fast

    Maximum number of updates

    		200

    Consecutive updates without improvements

    		50

    Maximum time (minutes)

    		5 minutes
  5. Check the Save optimization data box, otherwise your optimization data will not be saved and you will not be able to display the optimization curves.
  6. Click Run optimization.
  7. Type the name of the new representation and click OK.

    A steady value of 500 is reached very early for Function2. The free parameters as well as the Function2 value are updated in the tree.

    Important: Note that Real type parameters are displayed with nine decimal places (trailing zeros if any are not displayed). If you perform an optimization with other parameter types, the values are displayed according to the options specified in the Units tab of the Me > Preferences dialog box (General > Parameters and Measure).
  8. Replay the same scenario with a maximum number of updates of 50, then 20.
  9. Click OK or Cancel to exit the Optimization dialog box.
