    Macro Definition Documentation

    ◆ 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 3.1.1 never call presolver
