[Scip] Interrupting solver and resume later

[Gregor Hendel]

Hi,

one possibility to do so would be by means of an event handler which 
catches a frequent event ( SCIP_EVENTTYPE_NODEEVENT ), check if your 
time limit is exceeded by comparing against the
result of SCIPgetSolvingTime(scip), and if yes, check your bound conditions.

If the result matches your criteria, you can interrupt the solving 
process calling SCIPinterrupt(scip), or not if you want to continue the 
solving process.

Please see the documentation on How to implement Event Handlers 
<http://scip.zib.de/doc/html/EVENT.php>.

Best regards
Gregor
