gradient_tolerance


Stopping critiera based on L2 norm of gradient

Specification

Alias: none

Argument(s): REAL

Default: 1.e-4

Description

The gradient_tolerance control defines the threshold value on the L2 norm of the objective function gradient that indicates convergence to an unconstrained minimum (no active constraints). The gradient_tolerance control is defined for all gradient-based optimizers.
