XKTR_PARAM_GRADOPT

Description

Specifies how to compute the gradients of the objective and constraint functions.

Type

Integer

Values

1	(exact) User provides a routine for computing the exact gradients.
2	(forward) Knitro computes gradients by forward finite-differences.
3	(central) Knitro computes gradients by central finite differences.

Default value

Note

It is highly recommended to provide exact gradients if at all possible as this greatly impacts the performance of the code.
