# XSLP_EVTOL_R, SLPEVTOL_R

Description | Relative tolerance on total penalty costs
Type | Double
Topic areas | SLP, SLP-convergence, Tolerances
Default value | -1.0
Note | The solution will be regarded as having no active error vectors if one of the following applies: every penalty error vector and penalty delta vector has an activity less than XSLP_ERRORTOL_A; the sum of the cost contributions from all the penalty error and penalty delta vectors is less than XSLP_EVTOL_A; the sum of the cost contributions from all the penalty error and penalty delta vectors is less than XSLP_EVTOL_R * Obj where Obj is the current objective function value. 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-2 and 1e-6, but normally a magnitude larger than XSLP_ETOL_R.
