XSLP_CTOL

Description
Closure convergence tolerance
Type
Double
Default value
-1.0
Notes
The closure convergence criterion measures the change in value of a variable ( δX) relative to the value of its initial step bound ( B), against the closure convergence tolerance. If
δX < B * XSLP_CTOL
then the variable has converged on the closure convergence criterion.
If no explicit initial step bound is provided, then the test will not be applied and the variable can never converge on the closure 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.
