## Detailed Description

Holds information for recreating a subproblem by incremental change from the parent.

A CbcPartialNodeInfo object contains changes to the bounds and basis, and additional cuts, required to recreate a subproblem by modifying and augmenting the parent subproblem.

## Member Function Documentation

virtual void CbcPartialNodeInfo::applyToModel | ( | CbcModel * | model,
|  | CoinWarmStartBasis *& | basis,
|  | CbcCountRowCut ** | addCuts,
|  | int & | currentNumberCuts |
| ) |  |  | const`[virtual]`

Modify model according to information at node.

The routine modifies the model according to bound and basis change information at node and adds any cuts to the addCuts array.

Implements CbcNodeInfo.

virtual int CbcPartialNodeInfo::applyBounds | ( | int | iColumn,
|  | double & | lower,
|  | double & | upper,
|  | int | force |
| ) |  |  | `[virtual]`

Just apply bounds to one variable - force means overwrite by lower,upper (1=>infeasible).

Implements CbcNodeInfo.

virtual CbcNodeInfo* CbcPartialNodeInfo::buildRowBasis | ( | CoinWarmStartBasis & | basis | ) | const`[virtual]`

Builds up row basis backwards (until original model).

Returns NULL or previous one to apply . Depends on Free being 0 and impossible for cuts

Implements CbcNodeInfo.

virtual CbcNodeInfo* CbcPartialNodeInfo::clone | ( |  | ) | const`[virtual]`

Clone.

Implements CbcNodeInfo.

const CoinWarmStartDiff* CbcPartialNodeInfo::basisDiff | ( |  | ) | const`[inline]`

Basis diff information.

Definition at line 77 of file CbcPartialNodeInfo.hpp.

const int* CbcPartialNodeInfo::variables | ( |  | ) | const`[inline]`

Which variable (top bit if upper bound changing).

Definition at line 81 of file CbcPartialNodeInfo.hpp.

const double* CbcPartialNodeInfo::newBounds | ( |  | ) | const`[inline]`

Definition at line 85 of file CbcPartialNodeInfo.hpp.

int CbcPartialNodeInfo::numberChangedBounds | ( |  | ) | const`[inline]`

Number of bound changes.

Definition at line 89 of file CbcPartialNodeInfo.hpp.

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

Illegal Assignment operator.

Reimplemented from CbcNodeInfo.
