template<class CutType>
| void Cut< CutType >::duplicate_nodeinfo | ( | Pointer< MinlpNode > | oldnode, | |
| Pointer< MinlpNode > | newnode | |||
| ) |
Duplicates a CutNodeInfo and uses it for a new node.
Needed, when a node is splitted into new nodes.
Removed a node from the nodes-list, if it exists there.
- Returns:
- True, if the cut was local and this was the last node, which used this cut. False, else.
template<class CutType>
| pair<bool, bool> Cut< CutType >::set_inactivetime | ( | Pointer< MinlpNode > | node, | |
| bool | increase, | |||
| int | limit | |||
| ) |
Increases or resets the inactivity time for a node or global.
If this time exceeds a limit, the node is removed from the nodes set. For a global cut, the value of node is nonrelevant.
- Parameters:
-
increase Whether to increase the inactive timer or to set it to 0. limit The limit for inactivity.
- Returns:
- If the cut isn't used by any node anymore or was global and the time limit is exceeded, the first return value is true. False otherwise. If the cut is invalid for the node now, true is returned in second return value. False otherwise.
