		int	priority,
		int	minnnodes,
		SCIP_DECL_COMPRCOPY((*comprcopy))	,
		SCIP_DECL_COMPRFREE((*comprfree))	,

		SCIP_DECL_COMPREXITSOL((*comprexitsol))	,
		SCIP_DECL_COMPREXEC((*comprexec))	,
		SCIP_COMPRDATA *	comprdata
	)

creates a tree compression and includes it in SCIP.

Note: method has all compression callbacks as arguments and is thus changed every time a new callback is added in future releases; consider using SCIPincludeComprBasic() 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 tree compression
desc	description of tree compression
priority	priority of the tree compression
minnnodes	minimal number of nodes to call compression
comprdata	tree compression data

◆ SCIPincludeComprBasic()

SCIP_RETCODE SCIPincludeComprBasic	(	SCIP *	scip,

		const char *	desc,
		int	priority,
		int	minnnodes,
		SCIP_DECL_COMPREXEC((*comprexec))	,
		SCIP_COMPRDATA *	comprdata
	)

creates a tree compression 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 SCIPsetComprCopy(), SCIPsetComprFree(), SCIPsetComprInit(), SCIPsetComprExit(), SCIPsetComprInitsol(), and SCIPsetComprExitsol()

Note: if you want to set all callbacks with a single method call, consider using SCIPincludeCompr() instead

Parameters

scip	SCIP data structure
compr	pointer to tree compression
name	name of tree compression
desc	description of tree compression
priority	priority of the tree compression
minnnodes	minimal number of nodes to call the compression
comprdata	tree compression data
