XSLP_EVALUATE

Description
Evaluation strategy for user functions
Type
Integer
Values
0 
use derivatives where possible;
1 
always re-evaluate.
Default value
0
Notes
If a user function returns derivatives or returns more than one value, then it is possible for Xpress-SLP to estimate the value of the function from its derivatives if the new point of evaluation is sufficiently close to the original. Setting XSLP_EVALUATE to 1 will force re-evaluation of all functions regardless of how much or little the point of evaluation has changed.
Affects routines
XSLPevaluatecoef, XSLPevaluateformula
