XPRBnewcutsum

Purpose

Create a sum cut ( ∑_i x_i).

Synopsis

XPRBcut XPRBnewcutsum(XPRBprob prob, XPRBarrvar tv, char qrtype, double rhs, int mtype);

Arguments

prob

Reference to a problem.

Reference to an array of variables.

qrtype

Type of the cut:

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

Create the equality constraint ∑

⁴

_i=0

ty1_i = 9.

XPRBcut cut2;
XPRBarrvar ty1;
ty1 = XPRBnewarrvar(5, XPRB_PL, "arry1", 0, 500);
cut2 = XPRBnewcutsum(ty1, XPRB_E, 9, 3);

Further information

This function creates a simple sum constraint over all entries of an array of variables. It replaces calls to XPRBnewcut and XPRBaddcutterm.

Note:: all terms that are added to a cut must belong to the same problem as the cut itself.
