## Detailed Description

A class from which the real tree nodes should be derived from.

Some of the data that undoubtedly exist in the real tree node is replicated here for fast access. This class is used in the various comparison functions.

## Member Data Documentation

int CoinTreeNode::depth_`[private]`

The depth of the node in the tree.

Definition at line 78 of file CoinSearchTree.hpp.

int CoinTreeNode::fractionality_`[private]`

A measure of fractionality, e.g., the number of unsatisfied integrality requirements.

Definition at line 81 of file CoinSearchTree.hpp.

double CoinTreeNode::quality_`[private]`

Some quality for the node.

For normal branch-and-cut problems the LP relaxation value will do just fine. It is probably an OK approximation even if column generation is done.

Definition at line 85 of file CoinSearchTree.hpp.

double CoinTreeNode::true_lower_bound_`[private]`

A true lower bound on the node.

May be -infinity. For normal branch-and-cut problems the LP relaxation value is OK. It is different when column generation is done.

Definition at line 89 of file CoinSearchTree.hpp.

BitVector128 CoinTreeNode::preferred_`[private]`
