A function that tests the methods in the CglTwomir class.
The only reason for it not to be a member method is that this way it doesn't have to be compiled into the library. And that's a gain, because the library should be compiled with optimization on, but this method should be compiled with debugging.
std::string CglTwomir::probname_ |
Problem name.
