Detailed Description

cutbuffer.

Author:

Matthias Elf

This template class implements a buffer for constraints and variables which are generated during the cutting plane or column generation phase. There are two reasons why constraints/variables are buffered instead of being added immediately. First, the set of active constraints/variables should not be falsified during the cut/variable generation. Second, optionally a rank can be assigned to each buffered item. Then not all, but only the best items according to this rank are actually added.
