◆ SCIPaddConsNode()

SCIP_RETCODE SCIPaddConsNode ( SCIP scip,
SCIP_NODE node,
SCIP_CONS cons,
SCIP_NODE validnode 
)

adds constraint to the given node (and all of its subnodes), even if it is a global constraint; It is sometimes desirable to add the constraint to a more local node (i.e., a node of larger depth) even if the constraint is also valid higher in the tree, for example, if one wants to produce a constraint which is only active in a small part of the tree although it is valid in a larger part. In this case, one should pass the more global node where the constraint is valid as "validnode". Note that the same constraint cannot be added twice to the branching tree with different "validnode" parameters. If the constraint is valid at the same node as it is inserted (the usual case), one should pass NULL as "validnode". If the "validnode" is the root node, it is automatically upgraded into a global constraint, but still only added to the given node. If a local constraint is added to the root node, it is added to the global problem instead.

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 in one of the following stages of the SCIP solving process:
Parameters

◆ SCIPaddConsLocal()

SCIP_RETCODE SCIPaddConsLocal ( SCIP scip,
SCIP_CONS cons,
SCIP_NODE validnode 
)

adds constraint locally to the current node (and all of its subnodes), even if it is a global constraint; It is sometimes desirable to add the constraint to a more local node (i.e., a node of larger depth) even if the constraint is also valid higher in the tree, for example, if one wants to produce a constraint which is only active in a small part of the tree although it is valid in a larger part.

If the constraint is valid at the same node as it is inserted (the usual case), one should pass NULL as "validnode". If the "validnode" is the root node, it is automatically upgraded into a global constraint, but still only added to the given node. If a local constraint is added to the root node, it is added to the global problem instead.

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 in one of the following stages of the SCIP solving process:
Note
The same constraint cannot be added twice to the branching tree with different "validnode" parameters. This is the case due internal data structures and performance issues. In such a case you should try to realize your issue using the method SCIPdisableCons() and SCIPenableCons() and control these via the event system of SCIP.

◆ SCIPdelConsNode()

SCIP_RETCODE SCIPdelConsNode ( SCIP scip,
SCIP_NODE node,
SCIP_CONS cons 
)

disables constraint's separation, enforcing, and propagation capabilities at the given node (and all subnodes); if the method is called at the root node, the constraint is globally deleted from the problem; the constraint deletion is being remembered at the given node, s.t. after leaving the node's subtree, the constraint is automatically enabled again, and after entering the node's subtree, it is automatically disabled; this may improve performance because redundant checks on this constraint are avoided, but it consumes memory; alternatively, use SCIPdisableCons()

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.
