[Scip] how to set the time limit and get the gap at termination

[Stefan Heinz]

Hi,

there is no method which says something like SCIPsetTimelimit(). Since the 
time limit and all other limits (gap , memory, nodes, ...) are parameters. 
Therefore,  you have to use the parameter methods to set them and get the 
limits. In case of the time limit it looks like that:

SCIP_Real timelimit;

/* for getting the time limit */
SCIP_CALL( SCIPgetRealParam(scip, "limits/time", &timelimit) );


/* for setting the time limit */
SCIP_CALL( SCIPsetRealParam(subscip, "limits/time", timelimit) );

For the gap there is the function SCIPgetGap(scip) in scip.h.

Best Stefan
