StoreCuts Method (Int32, Int32, Int32[], Char[], Double[], Int64[], Cut[], Int32[], Double[])

Stores cuts into the cut pool, but does not apply them to the current node. These cuts must be explicitly loaded into the matrix using loadCuts before they become active.

Namespace:   Optimizer
Assembly:  xprsdn (in xprsdn.dll) Version: 44.01.01
Syntax
C# 
public void StoreCuts(
	int ncuts,
	int nodups,
	int[] cuttype,
	char[] rowtype,
	double[] rhs,
	long[] start,
	Cut[] cutind,
	int[] colind,
	double[] cutcoef
)

Parameters

ncuts
Type:  System.Int32
Number of cuts to add.
nodups
Type:  System.Int32
  • 0: do not exclude duplicates from the cut pool;
  • 1: duplicates are to be excluded from the cut pool;
  • 2: duplicates are to be excluded from the cut pool, ignoring cut type.
cuttype
Type:  System.Int32
Integer array of length ncuts containing the cut types. The cut types can be any integer and are used to identify the cuts.
rowtype
Type:  System.Char
Character array of length ncuts containing the row types:
  • L: indicates a <= row;
  • E: indicates an = row;
  • G: indicates a >= 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 offsets into the colind and dmtval 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.
cutind
Type:  Optimizer.Cut
Array of length ncuts where the pointers to the cuts will be returned.
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.
