@Regina,Yes, Wizard is a reference to the level of mastery that a solver must possess, and is one of those "which one of these words does not belong" solutions. There is a well-known *logarithmic* difficulty scale that has been used over 40 years for problem difficulty. It might be worth adapting: (after unknown), 00 easy - immediately solvable by someone willing to do it 10 simple - takes minutes 20 medium, average - quarter hour 30 moderate, an evening 40 difficult, challenging, non-trivial (term project, GSoC...) 50 unsolved, deep, requires a breakthrough, research (PhD dissertation) 60 intractable (that I just made up - probably not something that is technically feasible regardless of skill, Nobel Prize, P = NP, etc.)
Is this not similar to what Knuth used (uses) in his "Art of Computer Programming" series?
