Setting the Min. and Max. Step Sizes

For the Quasi Newton and Pattern Search optimizers, the step size is the difference in a variable's value between one solved design variation and the next. The step size is determined when Optimetrics locates the next design variation that should be solved in an effort to meet the cost function.

1. In the Setup Optimization dialog box, click the Variables tab.
2. Optimetrics displays Min Step and Max Step columns, with default values for each variable to be optimized.
3. In the Min Step text box, type the minimum step size value. Optionally, modify the unit system in the Units text box.
4. In the Max Step text box, type the maximum step size value. Optionally, modify the unit system in the Units text box.
5. Click OK.
   Tip:

   A value of zero is recommended for the minimum step size.
