Property Value
Type:
Int32
An
int specifying information about convergence.
Remarks Value | Description |
---|
0 | All convergence tests were met. |
1 | Scaled step tolerance was satisfied.
The current point may be an approximate local solution, or the
algorithm is making very slow progress and is not near a solution, or
StepTolerance is too big. |
2 | Scaled actual and predicted
reductions in the function are less than or equal to the relative
function convergence tolerance RelativeTolerance. |
3 | Iterates appear to be converging to
a noncritical point. Incorrect gradient information, a discontinuous
function, or stopping tolerances being too tight may be the cause.
|
4 | Five consecutive steps with the
maximum stepsize have been taken. Either the function is unbounded
below, or has a finite asymptote in some direction, or the
MaxStepsize is too small. |
