XPRSsetbranchbounds
Purpose
Specifies the bounds previously stored using
XPRSstorebounds that are to be applied in order to branch on a user
global entity. This routine can only be called from the user separate callback function,
XPRSaddcbsepnode.
Synopsis
int XPRS_CC XPRSsetbranchbounds(XPRSprob prob, void *bounds);
Arguments
|
prob
|
The current problem.
|
|
bounds
|
Pointer previously defined in a call to
XPRSstorebounds that references the stored bounds to be used to separate the node.
|
Example
This example defines a user separate callback function for the global search:
XPRSaddcbsepnode(prob,nodeSep,NULL,0);
where the function
nodeSep is defined as follows:
int nodeSep(XPRSprob prob, void *obj, int ibr, int iglsel,
int ifup, double curval)
{
void *index;
double dbd;
if( ifup )
{
dbd = ceil(curval);
XPRSstorebounds(prob, 1, &iglsel, "L", &dbd, &index);
}
else
{
dbd = floor(curval);
XPRSstorebounds(prob, 1, &iglsel, "U", &dbd, &index);
}
XPRSsetbranchbounds(prob, index);
return 0;
}
