Detailed Description

Holds complete information for recreating a subproblem.

A CbcFullNodeInfo object contains all necessary information (bounds, basis, and cuts) required to recreate a subproblem.

Todo:
While there's no explicit statement, the code often makes the implicit assumption that an CbcFullNodeInfo structure will appear only at the root node of the search tree. Things will break if this assumption is violated.

Member Function Documentation

virtual void CbcFullNodeInfo::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 information at node, creates a new basis according to information at node, but with the size passed in through basis, and adds any cuts to the addCuts array.

Note:
The basis passed in via basis is solely a vehicle for passing in the desired basis size. It will be deleted and a new basis returned.

Implements CbcNodeInfo.

virtual CbcNodeInfo* CbcFullNodeInfo::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* CbcFullNodeInfo::clone  )  const [virtual]
 

Clone.

Implements CbcNodeInfo.

CbcFullNodeInfo& CbcFullNodeInfo::operator= const CbcFullNodeInfo rhs  )  [private]
 

Illegal Assignment operator.


Member Data Documentation

CoinWarmStartBasis* CbcFullNodeInfo::basis_ [protected]
 

Full basis.

This MUST BE A POINTER to avoid cutting extra information in derived warm start classes.
