Detailed Description

NON Abstract Base Class for interfacing with cut generators or branching code or .

It is designed to be snapshot of a problem at a node in tree

The class may or may not own the arrays - see owned_

Querying a problem that has no data associated with it will result in zeros for the number of rows and columns, and NULL pointers from the methods that return arrays.
