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

Used to return the directives that have been loaded into a matrix. Priorities, forced branching directions and pseudo costs can be returned. If called after presolve, getDirs will get the directives for the presolved problem.

Namespace:   Optimizer
Assembly:  xprsdn (in xprsdn.dll) Version: 44.01.04
Syntax
C# 
public void GetDirs(
	out int p_ndir,
	int[] indices,
	int[] prios,
	char[] branchdirs,
	double[] uppseudo,
	double[] downpseudo
)

Parameters

p_ndir
Type:  System.Int32
Pointer to an integer where the number of directives will be returned.
indices
Type:  System.Int32
Integer array of length p_ndir containing the column numbers ( 0, 1, 2,...) or negative values corresponding to special ordered sets (the first set numbered -1, the second numbered -2,...). May be null if not required.
prios
Type:  System.Int32
Integer array of length p_ndir containing the priorities for the columns and sets, where columns/sets with smallest priority will be branched on first. May be null if not required.
branchdirs
Type:  System.Char
Character array of length p_ndir specifying the branching direction for each column or set:
  • U: the entity is to be forced up;
  • D: the entity is to be forced down;
  • N: not specified.
May be null if not required.
uppseudo
Type:  System.Double
Double array of length p_ndir containing the up pseudo costs for the columns and sets. May be null if not required.
downpseudo
Type:  System.Double
Double array of length p_ndir containing the down pseudo costs for the columns and sets. May be null if not required.
