creates a cut selector and includes it in SCIP
- Note
- this method has all cut selector callbacks as arguments and is thus changed every time a new callback is added in future releases; consider using SCIPincludeCutselBasic() and setter functions if you seek for a method which is less likely to change in future releases
- Parameters
-

Creates a cut selector and includes it in SCIP with its most fundamental callbacks.
All non-fundamental (or optional) callbacks as, e.g., init and exit callbacks, will be set to NULL. Optional callbacks can be set via specific setter functions, see SCIPsetCutselCopy(), SCIPsetCutselFree(), SCIPsetCutselInit(), SCIPsetCutselExit(), SCIPsetCutselInitsol(), and SCIPsetCutselExitsol()
- Note
- if you want to set all callbacks with a single method call, consider using SCIPincludeCutsel() instead
