get number of good (heavy) BbParaNodes in this pool
The following code is not a good idea, because only a node is received from a solver, LC can switch out if( globalBestBound > getBestDualBoundValue() ) globalBestBound = getBestDualBoundValue();
globalBestBound | global best bound value to evaluate goodness |
