creates a node selector and includes it in SCIP.

Note: method has all node selector callbacks as arguments and is thus changed every time a new callback is added in future releases; consider using SCIPincludeNodeselBasic() 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 node selector
desc	description of node selector
stdpriority	priority of the node selector in standard mode
memsavepriority	priority of the node selector in memory saving mode
nodeseldata	node selector data

		int	memsavepriority,
		SCIP_DECL_NODESELSELECT((*nodeselselect))	,
		SCIP_DECL_NODESELCOMP((*nodeselcomp))	,

	)

Creates a node 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 SCIPsetNodeselCopy(), SCIPsetNodeselFree(), SCIPsetNodeselInit(), SCIPsetNodeselExit(), SCIPsetNodeselInitsol(), and SCIPsetNodeselExitsol()

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

Parameters

scip	SCIP data structure
nodesel	reference to a node selector, or NULL
name	name of node selector
desc	description of node selector
stdpriority	priority of the node selector in standard mode
memsavepriority	priority of the node selector in memory saving mode
