@iammteah @tao In Bielefeld in the 1980's there was a special prof in physics. In the written exam the students were allowed to have one page with them - covered with definitions, formula, references in any font size. Even microfish were allowed. But reading only with eyes, not with technical help ;-) Better students had only little content on their pages.

@tao It might be an interesting business modell: generate (and sell) good "cheat sheets" for special areas of math, for instance "ramsey theory", "planar graph colourings", "Fullerene graphs"...

@tao Do you have an upper bound for the lengths of "cheat sheet prompts" in mind (in number of characters)? Of course links like "also use file ... for your answers" should not be allowed.

@tao I like the term and the concept of "artificial cleverness" - and in my eyes it should not get a negative conotation. Richard Feynman was a famous (theoretical) physicist (1918-1988), and he was a fan of cleverness. (See the anecdotes in his book "Surely you are joking Mr. Feynman") One of his proposals was: You should have your personal toolbox with a dozen or so special tricks. And always, when you listen to a talk where you are not really at home, go through the elements of your toolbox and look if you can apply one of them. I think, Feynman was a pragmatic scientist (including cleverness) in the best possible way.
