XSLP_ATOL_R

Description
Relative delta convergence tolerance
Type
Double
Default value
-1.0
Note
The relative delta convergence criterion assesses the change in value of a variable ( δX) relative to the value of the variable ( X), against the relative delta convergence tolerance. If
δX < X * XSLP_ATOL_R
then the variable has converged on the relative delta convergence criterion.

When the value is set to be negative, the value is adjusted automatically by SLP, based on the feasibility target XSLP_VALIDATIONTARGET_R. Good values for the control are usually fall between 1e-3 and 1e-6.
