XPRSdelcpcuts

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, const XPRScut mcutind[]);
Arguments
prob 
The current problem.
itype 
User defined cut type to match against.
interp 
Way in which the cut itype is interpreted:
-1 
match all cut types;
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.
