This is simply an interesting mathematical problem, perhaps only a zeroth-order approximation to real life of course. In real life, what you learn "interviewing" the first n candidates changes the criteria for candidates n+1...N. That is, you are growing too (if you are doing it right). Perhaps the characteristics you and your future mate require are actually innate, and s/he can be selected early? Possibly, but then you wouldn't know what you should be looking for, and arranged marriages are a better solution. Oh, yeah, and s/he has to like you back!
