	)

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:

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.

◆ SCIPdeactiveCons()

SCIP_EXPORT SCIP_RETCODE SCIPdeactiveCons	(	SCIP *	scip,
		SCIP_CONS *	cons
	)

calls constraint deactivation notification method of single constraint

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:

Note: This is an advanced method and should be used with caution. It may only be called for constraints that were not added to SCIP beforehand.

Parameters

scip	SCIP data structure
cons	constraint to notify

References FALSE, NULL, SCIP_CALL, SCIP_OKAY, SCIPcheckStage(), SCIPconsDeactive(), SCIPconsIsAdded(), Scip::set, and TRUE.

◆ SCIPprintCons()

SCIP_EXPORT SCIP_RETCODE SCIPprintCons	(	SCIP *	scip,
		SCIP_CONS *	cons,
		FILE *	file
	)

outputs constraint information to file stream via the message handler system

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:

Note: If the message handler is set to a NULL pointer nothing will be printed.; The file stream will not be flushed directly, this can be achieved by calling SCIPinfoMessage() printing a newline character.

Parameters

scip	SCIP data structure
cons	constraint
file	output file (or NULL for standard output)

◆ SCIPgetConsVars()

SCIP_EXPORT SCIP_RETCODE SCIPgetConsVars	(	SCIP *	scip,
		SCIP_CONS *	cons,
		SCIP_VAR **	vars,
		int	varssize,
		SCIP_Bool *	success
	)

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.

Precondition

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

Note: The success pointer indicates if all variables were copied into the vars arrray.; It might be that a constraint handler does not support this functionality, in that case the success pointer is set to FALSE.

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
success	pointer to store whether the variables are successfully copied

◆ SCIPgetConsNVars()

SCIP_EXPORT SCIP_RETCODE SCIPgetConsNVars	(	SCIP *	scip,
		SCIP_CONS *	cons,
		int *	nvars,
		SCIP_Bool *	success
	)

method to collect the number of variables of a constraint

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:

Note: The success pointer indicates if the contraint handler was able to return the number of variables; It might be that a constraint handler does not support this functionality, in that case the success pointer is set to FALSE

Parameters

scip	SCIP data structure
cons	constraint for which the number of variables is wanted
nvars	pointer to store the number of variables
success	pointer to store whether the constraint successfully returned the number of variables
