AddManagedCuts(Int32, Int32, Char[], Double[], Int32[], Int32[], Double[]) Method

Adds cuts to the Optimizer's internal cut pool from within the cutround callback set by addCbCutRound. The cuts will be added to an internal pool of cuts managed by the Optimizer. The Optimizer will use internal priorities to dynamically load violated cuts from this pool into branch-and-bound node problems and remove inactive cuts. Cuts can be either local or global. Cuts flagged as local are assumed to be valid only for the the current node of the branch-and-bound search or any of its descendants. Global cuts are assumed to be valid for the whole problem and might be used on any node of the branch-and-bound search tree. The cuts should be formulated in the original space of variables and will automatically be presolved.

Assembly: xprsdn (in xprsdn.dll) Version: 46.01.01+a3a330cd064168136e2506c7bff46e7bb9a4854d
Syntax
C# 
public void AddManagedCuts(
	int globalvalid,
	int ncuts,
	char[] rowtype,
	double[] rhs,
	int[] start,
	int[] colind,
	double[] cutcoef
)

Parameters

globalvalid   Int32
Nonzero if the cuts should be assumed to be valid for the whole problem. If zero, cuts will be assumed to be valid only for the current node and its descendants.
ncuts   Int32
Number of cuts to add.
rowtype   Char
Character array of length ncuts containing the row types:
  • L: indicates a <= row;
  • G: indicates a >= row;
  • E: indicates an = row.
rhs   Double
Double array of length ncuts containing the right hand side elements for the cuts.
start   Int32
Integer array containing offset into the colind and cutcoef arrays indicating the start of each cut. This array has one entry for each cut, plus one more entry indicating where an additional cut would start, if it were present.
colind   Int32
Integer array of length start[ncuts] containing the column indices in the cuts.
cutcoef   Double
Double array of length start[ncuts] containing the matrix values for the cuts.
