SCIPcreateCons()

		const char *	name,
		SCIP_CONSHDLR *	conshdlr,
		SCIP_CONSDATA *	consdata,
		SCIP_Bool	initial,

		SCIP_Bool	local,
		SCIP_Bool	modifiable,
		SCIP_Bool	dynamic,
		SCIP_Bool	removable,
		SCIP_Bool	stickingatnode
	)

creates and captures a constraint of the given constraint handler

Warning

If a constraint is marked to be checked for feasibility but not to be enforced, a LP or pseudo solution may be declared feasible even if it violates this particular constraint. This constellation should only be used, if no LP or pseudo solution can violate the constraint – e.g. if a local constraint is redundant due to the variable's local bounds.

Returns

SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See SCIP_RETCODE for a complete list of error codes.

Precondition

This method can be called if scip is in one of the following stages:

• SCIP_STAGE_PROBLEM
• SCIP_STAGE_TRANSFORMING
• SCIP_STAGE_INITPRESOLVE
• SCIP_STAGE_PRESOLVING
• SCIP_STAGE_EXITPRESOLVE
• SCIP_STAGE_PRESOLVED
• SCIP_STAGE_INITSOLVE
• SCIP_STAGE_SOLVING
• SCIP_STAGE_EXITSOLVE

Note

the constraint gets captured, hence at one point you have to release it using the method SCIPreleaseCons()

Parameters

scip	SCIP data structure
cons	pointer to constraint
name	name of constraint
conshdlr	constraint handler for this constraint
consdata	data for this specific constraint
initial	should the LP relaxation of constraint be in the initial LP? Usually set to TRUE. Set to FALSE for 'lazy constraints'.
separate	should the constraint be separated during LP processing? Usually set to TRUE.
enforce	should the constraint be enforced during node processing? TRUE for model constraints, FALSE for additional, redundant constraints.
check	should the constraint be checked for feasibility? TRUE for model constraints, FALSE for additional, redundant constraints.
propagate	should the constraint be propagated during node processing? Usually set to TRUE.
local	is constraint only valid locally? Usually set to FALSE. Has to be set to TRUE, e.g., for branching constraints.
modifiable	is constraint modifiable (subject to column generation)? Usually set to FALSE. In column generation applications, set to TRUE if pricing adds coefficients to this constraint.
dynamic	is constraint subject to aging? Usually set to FALSE. Set to TRUE for own cuts which are separated as constraints.
removable	should the relaxation be removed from the LP due to aging or cleanup? Usually set to FALSE. Set to TRUE for 'lazy constraints' and 'user cuts'.
stickingatnode	should the constraint always be kept at the node where it was added, even if it may be moved to a more global node? Usually set to FALSE. Set to TRUE to for constraints that represent node data.

SCIPdisableCons()

SCIP_RETCODE SCIPdisableCons	(	SCIP *	scip,

disables constraint's separation, propagation, and enforcing capabilities, s.t. the constraint is not propagated, separated, and enforced anymore until it is enabled again with a call to SCIPenableCons(); in contrast to SCIPdelConsLocal() and SCIPdelConsNode(), the disabling is not associated to a node in the tree and does not consume memory; therefore, the constraint is neither automatically enabled on leaving the node nor automatically disabled again on entering the node again; note that the constraints enforcing capabilities are necessary for the solution's feasibility, if the constraint is a model constraint; that means, you must be sure that the constraint cannot be violated in the current subtree, and you have to enable it again manually by calling SCIPenableCons(), if this subtree is left (e.g. by using an appropriate event handler that watches the corresponding variables' domain changes)

Returns

SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See SCIP_RETCODE for a complete list of error codes.

method to collect the variables of a constraint

If the number of variables is greater than the available slots in the variable array, nothing happens except that the success point is set to FALSE. With the method SCIPgetConsNVars() it is possible to get the number of variables a constraint has in its scope.

Returns

SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See SCIP_RETCODE for a complete list of error codes.

Parameters

scip	SCIP data structure
cons	constraint for which the variables are wanted
vars	array to store the involved variable of the constraint
varssize	available slots in vars array which is needed to check if the array is large enough
