My take-away was that D-Wave II can beat the classical solvers in a subset of problems, but not all. The OP hopes to examine his data set and isolate the set of problems at which D-Wave II is consistently faster than the classical solvers. Perhaps at that point the classical solvers could be furthered improved to become faster than D-Wave II. As the set of problems is further narrowed, someday we may have a set of problems at which D-Wave II cannot be beat by a classical solver. Perhaps that will be evidence that D-Wave II is a quantum machine. Or not.
