Detailed Description

template<class Master, class Slave>
class CQKnPClone< Master, Slave >

Class for cross-testing solvers of the Continuous Quadratic Knapsack Problem implemented as derived object of the class CQKnPClass [see CQKnPClass.h].

The class is template over two objects, a "Master" one and a "Slave" one, that are assumed to be both derived from CQKnPClass; it derives from the Master class, and creates an object of the Slave class. Every call to a method is "reflected" on both objects. In some cases, checks are performed that the results agree.

The rationale for having CQKnPClone to derive from the Master class is that some methods (typically, these that read back the data of the problem) do not need to be redefined, as being CQKnPClone derived from Master the Master:: implementation of the method is automatically used (of course this implies that no checks are done that Master and Slave agree on which data they have, which perhaps should be done).
