C++ wrapper for variable pricer.
This class defines the interface for variable pricer implemented in C++. Note that there is a pure virtual function (this function has to be implemented). This function is: scip_redcost().

delay | should the pricer be delayed until no other pricers or already existing problem variables with negative reduced costs are found? if this is set to FALSE it may happen that the pricer produces columns that already exist in the problem (which are also priced in by the default problem variable pricing in the same round) |
