Description
Bit map describing the cascading to be used
Type
Integer
Topic areas
SLP, Cascading
Values
Bit
Meaning
0 
XPRS_SLPCASCADE_ALL Apply cascading to all variables with determining rows.
1 
XPRS_SLPCASCADE_COEF_VAR Apply cascading to SLP variables which appear in coefficients and which would change by more than FEASTOL.
2 
XPRS_SLPCASCADE_ALL_COEF_VAR Apply cascading to all SLP variables which appear in coefficients.
3 
XPRS_SLPCASCADE_STRUCT_VAR Apply cascading to SLP variables which are structural and which would change by more than FEASTOL.
4 
XPRS_SLPCASCADE_ALL_STRUCT_VAR Apply cascading to all SLP variables which are structural.
5 
XPRS_SLPCASCADE_SECONDARY_GROUPS Create secondary order groupping DR rows with instantiated user functions together in the order.
6 
XPRS_SLPCASCADE_DRCOL_PREVOUSVALUE In cases where the determining column is below SLPDRCOLTOL, fix at the previous rather than current value.
7 
XPRS_SLPCASCADE_DRCOL_PVRANGE In cases where the determining column is below SLPDRCOLTOL, fix within a range SLPDRFIXRANGE of previous value.
8 
XPRS_SLPCASCADE_AUTOAPPLY Automatically determine whether to apply cascading.
Default value
257
Note
Normal cascading (bit 0) uses determining rows to recalculate the values of variables to be consistent with values already available or already recalculated.
Other bit settings are normally required only in quadratic programming where some of the SLP variables are in the objective function. The values of such variables may need to be corrected if the corresponding update row is slightly infeasible.
