Does SAT exhibit fractal behavior? Joost J. Joosten, Grant Olney Passmore Abstract: In this paper we study the structure of the set SAT of all satisfiable propositional logical formulas. In particular we raise the question whether the distribution of SAT within the set A of all propositional formulas exhibits fractal behavior. This answer is of course relative to a metric on A. We show that for one such metric there is strong evidence that the distribution does indeed behave wildly. Next we look at an alternative metric.
