Load sets of standard tolerance values into an SLP problem

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 SLPTol[18];
for (i=0;i<9;i++) SLPTol[i] = 0.005;
SLPTol[9] = 0;
for (i=10;i<18;i=i+2) SLPTol[i] = 0.01;
for (i=11;i<18;i=i+2) SLPTol[i] = 0.001;
XSLPloadtolsets(Prob, 2, SLPTol);

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

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.

Once created, a tolerance set can be used to set the tolerances for any SLP variable.

If a tolerance value is zero, then the default tolerance will be used instead. To force the use of a zero tolerance, use the XSLPchgtolset function and set the Status variable appropriately.

See the section "Convergence Criteria" for a fuller description of tolerances and their uses.

The XSLPload... functions load items into the SLP problem. Any existing items of the same type are deleted first. The corresponding XSLPadd... functions add or replace items leaving other items of the same type unchanged.
