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

Adds cuts directly to the matrix at the current node. The cuts will automatically be added to the cut pool. Cuts added to a node will automatically be inherited on any descendant node, unless explicitly deleted with a call to delCuts.

Assembly:  xprsdn (in xprsdn.dll) Version: 44.01.04
Syntax
C# 
public void AddCuts(
	int ncuts,
	int[] cuttype,
	char[] rowtype,
	double[] rhs,
	int[] start,
	int[] colind,
	double[] cutcoef
)

Parameters

ncuts
Type:  System.Int32
Number of cuts to add.
cuttype
Type:  System.Int32
Integer array of length ncuts containing the user assigned cut types. The cut types can be any integer chosen by the user, and are used to identify the cuts in other cut manager routines using user supplied parameters. The cut type can be interpreted as an integer or a bitmap - see delCuts.
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.Int32
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.
