Derivative testing

Type : Selection

Range : The settings listed below

Default : Do not perform derivative tests

This option enables the derivative checker. If this option is enabled, a (slow!) derivative test will be performed before the optimization. The test is performed at the user provided starting point and marks derivative values that seem suspicious. Possible values are:

  • Do not perform derivative tests

  • Test first derivatives at starting point

  • Test first and second derivatives at starting point
