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

public void GetMIPEntities(
	out int p_nentities,
	out int p_nsets,
	char[] coltype,
	int[] colind,
	double[] limit,
	char[] settype,
	int[] start,
	int[] setcols,
	double[] refval
)

Parameters

p_nentities

Type:  System.Int32
Pointer to the integer where the number of binary, integer, semi-continuous, semi-continuous integer and partial integer entities will be returned. This is equal to the problem attribute MIPENTS. May be null.

p_nsets

Type:  System.Int32
Pointer to the integer where the number of SOS1 and SOS2 sets will be returned. It can be retrieved from the problem attribute SETS. May be null.

coltype

Type:  System.Char
Character array of length p_nentities where the entity types will be returned. The types will be one of:

• B: binary variables;
• I: integer variables;
• P: partial integer variables;
• S: semi-continuous variables;
• R: semi-continuous integer variables.

colind

Type:  System.Int32
Integer array of length p_nentities where the column indices of the MIP entities will be returned.

limit

Type:  System.Double
Double array of length p_nentities where the limits for the partial integer variables and lower bounds for the semi-continuous and semi-continuous integer variables will be returned (any entries in the positions corresponding to binary and integer variables will be meaningless).

settype

Type:  System.Char
Character array of length p_nsets where the set types will be returned. The set types will be one of:

• 1: SOS1 type sets;
• 2: SOS2 type sets.

start

Type:  System.Int32
Integer array where the offsets into the setcols and refval arrays indicating the start of the sets will be returned. This array must be of length p_nsets+1, the final element will contain the offset where set p_nsets+1 would start and equals the length of the setcols and refval arrays, SETMEMBERS.

setcols

Type:  System.Int32
Integer array of length SETMEMBERS where the columns in each set will be returned.

refval

Type:  System.Double
Double array of length SETMEMBERS where the reference row entries for each member of the sets will be returned. These define the order for SOS2 constraints and may be used in branching for both types.
