Purpose
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,
XPRSgetdirs will get the directives for the
presolved problem.
Synopsis
int XPRS_CC XPRSgetdirs(XPRSprob prob, int *ndir, int mcols[], int mpri[], char qbr[], double dupc[], double ddpc[]);
Arguments
|
prob
|
The current problem.
|
|
ndir
|
Pointer to an integer where the number of directives will be returned.
|
|
mcols
|
Integer array of length 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,...).
|
|
mpri
|
Integer array of length ndir containing the priorities for the columns and sets.
|
|
qbr
|
Character array of length 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.
|
|
|
dupc
|
Double array of length ndir containing the up pseudo costs for the columns and sets.
|
|
ddpc
|
Double array of length ndir containing the down pseudo costs for the columns and sets.

Further information
1. The value
ndir denotes the number of directives, at most
MIPENTS, obtainable with
XPRSgetintattrib(prob,XPRS_MIPENTS,&
mipents);.
2. Any of the arguments except prob and ndir may be NULL
