AddManagedCuts Method (Int32, Int32, Char[], Double[], Int64[], Int32[], Double[])

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: 45.01.01+08e34f16483948c1342f17c81d958e08c9f72d93
Syntax
C# 
public void AddManagedCuts(
	int globalvalid,
	int ncuts,
	char[] rowtype,
	double[] rhs,
	long[] start,
	int[] colind,
	double[] cutcoef
)

Parameters

globalvalid
Type:  System.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
Type:  System.Int32
Number of cuts to add.
rowtype
Type:  System.Char
Character array of length ncuts containing the row types:
  • L: indicates a <= row;
  • G: indicates a >= row;
  • E: indicates an = row.
rhs
Type:  System.Double
Double array of length ncuts containing the right hand side elements for the cuts.
start
Type:  System.Int64
Integer array containing offset into the colind and cutcoef arrays indicating the start of each cut. This array is of length ncuts+1 with the last element, start[ncuts], being where cut ncuts+1 would start.
colind
Type:  System.Int32
Integer array of length start[ncuts] containing the column indices in the cuts.
cutcoef
Type:  System.Double
Double array of length start[ncuts] containing the matrix values for the cuts.
