XPRSdelcpcuts

---

Purpose

During the Branch and Bound search, cuts are stored in the cut pool to be applied at descendant nodes. These cuts may be removed from a given node using XPRSdelcuts, but if this is to be applied in a large number of cases, it may be preferable to remove the cut completely from the cut pool. This is achieved using XPRSdelcpcuts.

Synopsis

int XPRS_CC XPRSdelcpcuts(XPRSprob prob, int itype, int interp, int ncuts, XPRScut mcutind[]);

Arguments

prob	The current problem.
itype	Cut type.
interp	Way in which the cut type is interpreted: -1  drop all cuts; 1  treat cut types as numbers; 2  treat cut types as bit maps - delete if any bit matches any bit set in itype; 3  treat cut types as bit maps - delete if all bits match those set in itype.
ncuts	The number of cuts to delete. A value of -1 indicates delete all cuts.
mcutind	Array containing pointers to the cuts which are to be deleted. This array may be NULL if ncuts is -1, otherwise it has length ncuts.
