XPRBaddcutarrterm

Purpose

Add multiple terms to a cut.

Synopsis

int XPRBaddcutarrterm(XPRBcut cut, XPRBarrvar av, double *coeff);

Arguments

cut

Reference to a cut.

av

Reference to an array of variables.

coeff

Values to be added to the coefficients of the variables in the array (the number of coefficients must correspond to the size of the array of variables).

Return value

0 if function executed successfully, 1 otherwise.

Example

Add the term
⁴

_i=0

cr_i· ty1_i to the cut cut1.
XPRBcut cut1;
XPRBarrvar ty1;
double cr[] = {2.0, 13.0, 15.0, 6.0, 8.5};
XPRBprob expl1;
expl1 = XPRBnewprob("cutexample");
ty1 = XPRBnewarrvar(expl1, 5, XPRB_PL, "arry1", 0, 500); 
cut1 = XPRBnewcut(expl1, XPRB_E, 1);
XPRBaddcutarrterm(cut1, ty1, cr);
Further information

This function adds multiple terms to a cut, the variables coming from array av and the corresponding coefficients from coeff. If the cut already has a term with one of the variables, the corresponding value from coeff is added to its coefficient.
