## Member Function Documentation

AbcTreeNode& AbcTreeNode::operator= | ( | const AbcTreeNode & |  | ) | `[private]`

Reimplemented from AlpsTreeNode.

virtual AlpsTreeNode* AbcTreeNode::createNewTreeNode | ( | AlpsNodeDesc *& | desc | ) | const`[virtual]`

The purpose of this function is be able to create the children of a node after branching.

Implements AlpsTreeNode.

virtual int AbcTreeNode::process | ( | bool | isRoot = `false`,
|  | bool | rampUp = `false` |
| ) |  |  | `[virtual]`

Performing the bounding operation.

int AbcTreeNode::chooseBranch | ( | AbcModel * | model,
|  | bool & | strongFound |
| ) |  |  |

Select the branch variable.

Return value:

- 0: A branching object has been installed
- -1: A monotone object was discovered
- -2: An infeasible object was discovered

double AbcTreeNode::getObjValue | ( |  | ) | const`[inline]`

Query/set the objective value (could be approximately or not exit) of the node.

Definition at line 125 of file AbcTreeNode.h.

void AbcTreeNode::setObjValue | ( | const double | objValue | ) | `[inline]`

Query/set the objective value (could be approximately or not exit) of the node.

Definition at line 126 of file AbcTreeNode.h.

virtual AlpsEncoded* AbcTreeNode::encode | ( |  | ) | const`[virtual]`

This method should encode the content of the object and return a pointer to the encoded form.

NOTE: This default implementation can not be used when the memory of data members is not continously allocated, for example, some data members are pointers, STL set, map, etc.

Reimplemented from AlpsKnowledge.
