XPRSloadpresolvedirs


Purpose
Loads directives into the presolved matrix.
Synopsis
int XPRS_CC XPRSloadpresolvedirs(XPRSprob prob, int ndir, const int mcols[], const int mpri[], const char qbr[], const double dupc[], const double ddpc[]);
Arguments
prob 
The current problem.
ndir 
Number of directives.
mcols 
Integer array of length ndir containing the column numbers. A negative value indicates a set number ( -1 being the first set, -2 the second, and so on).
mpri 
Integer array of length ndir containing the priorities for the columns or sets. May be NULL if not required.
qbr 
Character array of length ndir specifying the branching direction for each column or set:
the entity is to be forced up;
the entity is to be forced down;
not specified.
May be NULL if not required.
dupc 
Double array of length ndir containing the up pseudo costs for the columns or sets. May be NULL if not required.
ddpc 
Double array of length ndir containing the down pseudo costs for the columns or sets. May be NULL if not required.
Example
The following loads priority directives for column 0 in the matrix:
int mcols[] = {0}, mpri[] = {1};
...
XPRSmipoptimize(prob,"l");
XPRSloadpresolvedirs(prob,1,mcols,mpri,NULL,NULL,NULL);
XPRSmipoptimize(prob,"");
