Function Documentation

SCIP_RETCODE SCIPcreateObjVar	(	SCIP *	scip,
		SCIP_VAR **	var,
		const char *	name,
		SCIP_Real	lb,
		SCIP_Real	ub,
		SCIP_Real	obj,
		SCIP_VARTYPE	vartype,
		SCIP_Bool	initial,
		SCIP_Bool	removable,
		scip::ObjVardata *	objvardata,
		SCIP_Bool	deleteobject
	)

create and capture problem variable and associates the given variable data with the variable; if variable is of integral type, fractional bounds are automatically rounded

Parameters

scip	SCIP data structure
var	pointer to variable object
name	name of variable, or NULL for automatic name creation
lb	lower bound of variable
ub	upper bound of variable
obj	objective function value
vartype	type of variable
initial	should var's column be present in the initial root LP?
removable	is var's column removable from the LP (due to aging or cleanup)?
objvardata	user variable data object
deleteobject	should the user variable data object be deleted when variable is freed?

scip::ObjVardata* SCIPgetObjVardata	(	SCIP *	scip,
		SCIP_VAR *	var
	)

gets user variable data object for given problem variable Warning! This method should only be called after a variable was created with SCIPcreateObjVar(). Otherwise, a segmentation fault may arise, or an undefined pointer is returned.

Parameters

scip	SCIP data structure
var	problem variable
