XSLPaddtolsets

Purpose
This subroutine is deprecated and will be removed in a future release.
Add sets of standard tolerance values to an SLP problem.
Topic areas
SLP, SLP-convergence
Synopsis
int XPRS_CC XSLPaddtolsets(XSLPprob prob, int ntol, double *tol);
Arguments
prob 
The current SLP problem.
ntol 
The number of tolerance sets to be added.
tol 
Double array of ( ntol * 9) items containing the 9 tolerance values for each set in order.
Example
The following example creates two tolerance sets: the first has values of 0.005 for all tolerances; the second has values of 0.001 for relative tolerances (numbers 2,4,6,8), values of 0.01 for absolute tolerances (numbers 1,3,5,7) and zero for the closure tolerance (number 0). 
double tol[18];
for (i=0;i<9;i++) tol[i] = 0.005;
tol[9] = 0;
for (i=10;i<18;i=i+2) tol[i] = 0.01;
for (i=11;i<18;i=i+2) tol[i] = 0.001;
XSLPaddtolsets(prob, 2, tol);
Further information
1. A tolerance set is an array of 9 values containing the following tolerances:

Entry / Bit Tolerance XSLP constant XSLP bit constant
0 Closure tolerance (TC) XSLP_TOLSET_TC XSLP_TOLSETBIT_TC
1 Absolute delta tolerance (TA) XSLP_TOLSET_TA XSLP_TOLSETBIT_TA
2 Relative delta tolerance (RA) XSLP_TOLSET_RA XSLP_TOLSETBIT_RA
3 Absolute coefficient tolerance (TM) XSLP_TOLSET_TM XSLP_TOLSETBIT_TM
4 Relative coefficient tolerance (RM) XSLP_TOLSET_RM XSLP_TOLSETBIT_RM
5 Absolute impact tolerance (TI) XSLP_TOLSET_TI XSLP_TOLSETBIT_TI
6 Relative impact tolerance (RI) XSLP_TOLSET_RI XSLP_TOLSETBIT_RI
7 Absolute slack tolerance (TS) XSLP_TOLSET_TS XSLP_TOLSETBIT_TS
8 Relative slack tolerance (RS) XSLP_TOLSET_RS XSLP_TOLSETBIT_RS


2. The XSLP_TOLSET constants can be used to access the corresponding entry in the value arrays, while the XSLP_TOLSETBIT constants are used to set or retrieve which tolerance values are used for a given SLP variable.
3. Once created, a tolerance set can be used to set the tolerances for any SLP variable.
4. If a tolerance value is zero, then the default tolerance will be used instead. To force the use of a tolerance, use the XSLPchgtolset function and set the Status variable appropriately.
5. See the section Convergence criteria for a fuller description of tolerances and their uses.
6. The add functions load additional items into the SLP problem. The corresponding load functions delete any existing items first.
