If I'm understanding this right, I'm pretty sure this is not in fact just a wizard. It's using people's answers to "which of these is better" to learn an objective function that can later be used for optimization. A wizard is just presenting explicit choices. Making one requires knowing all the possible paths and results in advance. You could I suppose have an "implicit wizard", where every choice was in terms of "Which of these two examples do you prefer?" rather than explicitly stating what the user was choosing between, but that would ultimately just be a more confusing version of an explicit wizard -- it would still require you to program in all the possible paths and results in advance. That's much less interesting than this.
