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.

| 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
