Synopsis
int XPRS_CC XPRSloadpresolvedirs(XPRSprob prob, int ndirs, const int colind[], const int priority[], const char dir[], const double uppseudo[], const double downpseudo[]);
Arguments
prob 
The current problem.
ndirs 
Number of directives.
colind 
Integer array of length ndirs containing the column numbers. A negative value indicates a set number ( -1 being the first set, -2 the second, and so on).
priority 
Integer array of length ndirs containing the priorities for the columns or sets. May be NULL if not required.
dir 
Character array of length ndirs 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 
Double array of length ndirs containing the up pseudo costs for the columns or sets. May be NULL if not required.
downpseudo 
Double array of length ndirs 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 colind[] = {0}, priority[] = {1};
...
XPRSmipoptimize(prob,"l");
XPRSloadpresolvedirs(prob,1,colind,priority,NULL,NULL,NULL);
XPRSmipoptimize(prob,"");
