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
scipSCIP data structure
conspointer to constraint
namename of constraint
conshdlrconstraint handler for this constraint
consdatadata for this specific constraint
initialshould the LP relaxation of constraint be in the initial LP? Usually set to TRUE. Set to FALSE for 'lazy constraints'.
separateshould the constraint be separated during LP processing? Usually set to TRUE.
enforceshould the constraint be enforced during node processing? TRUE for model constraints, FALSE for additional, redundant constraints.
checkshould the constraint be checked for feasibility? TRUE for model constraints, FALSE for additional, redundant constraints.
propagateshould the constraint be propagated during node processing? Usually set to TRUE.
localis constraint only valid locally? Usually set to FALSE. Has to be set to TRUE, e.g., for branching constraints.
modifiableis constraint modifiable (subject to column generation)? Usually set to FALSE. In column generation applications, set to TRUE if pricing adds coefficients to this constraint.
dynamicis constraint subject to aging? Usually set to FALSE. Set to TRUE for own cuts which are separated as constraints.
removableshould 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'.
stickingatnodeshould 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.

parses constraint information (in cip format) out of a string; if the parsing process was successful a constraint is creates and captures;

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:
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.
Parameters
scipSCIP data structure
conspointer to store constraint
strstring to parse for constraint
initialshould the LP relaxation of constraint be in the initial LP? Usually set to TRUE. Set to FALSE for 'lazy constraints'.
separateshould the constraint be separated during LP processing? Usually set to TRUE.
enforceshould the constraint be enforced during node processing? TRUE for model constraints, FALSE for additional, redundant constraints.
checkshould the constraint be checked for feasibility? TRUE for model constraints, FALSE for additional, redundant constraints.
propagateshould the constraint be propagated during node processing? Usually set to TRUE.
localis constraint only valid locally? Usually set to FALSE. Has to be set to TRUE, e.g., for branching constraints.
modifiableis constraint modifiable (subject to column generation)? Usually set to FALSE. In column generation applications, set to TRUE if pricing adds coefficients to this constraint.
dynamicis constraint subject to aging? Usually set to FALSE. Set to TRUE for own cuts which are separated as constraints.
removableshould 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'.
stickingatnodeshould 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.
successpointer to store if the paring process was successful

◆ 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)

disables constraint's separation capabilities s.t. the constraint is not separated anymore until the separation is enabled again with a call to SCIPenableConsSeparation(); 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
