Second Order Correction

Range

The settings listed below

Default

At some iterations

This option indicates whether or not the second order correction (SOC) option should be used. A second order correction may be beneficial for problems with highly nonlinear constraints. Possible values are:

• None

• At some iterations

• Always

With setting ‘At some iterations’ second order correction steps may be attempted on some iterations. With setting ‘Always’ second order correction steps are always attempted if the original step is rejected and there are nonlinear constraints.
