# XSLP_ETOL_R, SLPETOL_R

Description | Relative tolerance on penalty vectors
Type | Double
Topic areas | SLP, Tolerances
Default value | 0.0001
Note | For each penalty error vector, the contribution to its constraint is calculated, together with the total positive and negative contributions to the constraint from other vectors. If its contribution is less than XSLP_ETOL_A or less than Positive*XSLP_ETOL_R or less than abs(Negative)*XSLP_ETOL_R then it will be regarded as insignificant and will not have its penalty increased. 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.
