		SCIP_DECL_CUTSELSELECT((*cutselselect))	,
		SCIP_CUTSELDATA *	cutseldata
	)

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

scip	SCIP data structure
name	name of cut selector
desc	description of cut selector
priority	priority of the cut selector
cutseldata	cut selector data

Definition at line 50 of file scip_cutsel.c.

◆ SCIPincludeCutselBasic()

SCIP_RETCODE SCIPincludeCutselBasic	(	SCIP *	scip,

		const char *	name,
		const char *	desc,
		int	priority,
		SCIP_DECL_CUTSELSELECT((*cutselselect))	,
		SCIP_CUTSELDATA *	cutseldata
	)

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

Parameters

scip	SCIP data structure
cutsel	reference to a cut selector, or NULL
name	name of cut selector
desc	description of cut selector
priority	priority of the cut selector in standard mode
cutseldata	cut selector data
