XPRBnewcutarrsum

---

Purpose

Create a sum cut with individual coefficients (_i c_i· x_i).

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

c_i· ty1_i 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.
