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 presolving disabled
