[SCIP] Get cut information each time a cut is generated

[Benjamin Müller]

Dear Ziye,

you can add an event handler that catches the SCIP_EVENTTYPE_ROWADDEDLP 
event and then prints the information of the cut in the 
SCIP_DECL_EVENTEXEC callback. Here

	http://scip.zib.de/doc/html/EVENT.php

you can find a guideline of how to write such an event handler. Please 
also have a look at the scip/examples/Eventhdlr directory of SCIP, which 
contains two different event handler examples. The first one catches the 
event SCIP_EVENTTYPE_BESTSOLFOUND and the second one writes primal and 
dual bounds for all open nodes into a file.

You can write me a pm if you need more help in writing your event handler.

Regards,
Benny
