XPRBnewcutarrsum

XPRBnewcutarrsum


Purpose
Create a sum cut with individual coefficients ( ∑i ci· xi).
Synopsis
XPRBcut XPRBnewcutarrsum(XPRBprob prob, XPRBarrvar av, double *cof, char qrtype, double rhs, int mtype);
Arguments
prob 
Reference to a problem.
av 
Reference to an array of variables.
cof 
Array of constant coefficients for all elements of (at least size of av).
qrtype 
Type of the cut:
XPRB_L 
(inequality)
XPRB_G 
(inequality)
XPRB_E 
= (equation)
rhs 
RHS value of the cut.
mtype 
Cut classification or identification number.
Return value
Reference to the new cut if function executed successfully, NULL otherwise.
Example
The following creates the inequality constraint
4
i=0
ci· ty1i ≥ 7
.
XPRBcut cut4;
XPRBarrvar ty1;
double c[] = {2.5, 4.0, 7.2, 3.0, 1.8};
ty1 = XPRBnewarrvar(5, XPRB_PL, "arry1", 0, 500);
cut4 = XPRBnewcutarrsum(ty1, c, XPRB_G, 7.0, 18);
Further information
This function creates a cut consisting of the sum over variables multiplied by the coefficients indicated by array cof. This function replaces XPRBnewcut and XPRBaddcutterm.
Note:
all terms that are added to a cut must belong to the same problem as the cut itself.
