TOptStopReason Type

Summary

Why the main loop in optimization stopped.

Declaration

TOptStopReason = (OptResNotFound, OptResSmallGrad, OptResSingular, OptResSmallStep,
                    OptResZeroStep, OptResBigLambda, OptResMaxIter, OptResConverged,
                    optResSmallJacobian);

Value	Description
OptResNotFound	The algorithm did not find minimum (within given tolerance).
OptResSmallGrad	The gradient C-Norm is bellow given gradient tolerance.
OptResSingular	The inverse Hessian matrix is near singular.
OptResSmallStep	Iteration x step is less than EPS.
OptResZeroStep	Iteration x step is zero.
OptResBigLambda	(Marquardt) Lambda is more than 1000.
OptResMaxIter	Number of iterations has reached the MaxIter.
OptResConverged	Number of iterations is less than MaxIter and parameters are within given tolerance.

Description

Defines why the main loop in optimization routine was stopped.
