[Scip] SCIPsetMessagehdlr(NULL) question

[gamrath@zib.de]

Hi Nikolaj,

you can control the amount of output by the parameter "display/verblevel";
it ranges from SCIP_VERBLEVEL_NONE (=0) to SCIP_VERBLEVEL_FULL (=5), per
default it is SCIP_VERBLEVEL_HIGH (=4). So, you can set this parameter in
your sub-SCIP to SCIP_VERBLEVEL_NONE (or 0) in order to get no messages
other than error and warning messages.

You can do this by the following command for the instance of SCIP named
subscip:

/* disable output to console */
SCIP_CALL( SCIPsetIntParam(subscip, "display/verblevel",
SCIP_VERBLEVEL_NONE) );

Best, Gerald
