# problem.loadtolsets

Purpose
This subroutine is deprecated and will be removed in a future release.
Load sets of standard tolerance values into an SLP problem
Synopsis
`problem.loadtolsets(slptol)`
Argument

tol | Array of 9h 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).

    tol = 9*[0.005]+[0]+[0.01,0.001]*4
    p.loadtolsets(tol)

Further information
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 tolerance, use the problem.chgtolset function and set the Status variable appropriately.

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

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