◆ SCIP_PRESOLTIMING_NONE

#define SCIP_PRESOLTIMING_NONE   0x002u

presolving execution timing flags

Note
: in contrast to other timings, these timings need to start from 0x0002u in order to avoid confusion with the now obsolete '(presol)delay' boolean flag used until SCIP version 3.1.1presolving disabled
