1/3–2/3 conjecture this connection with the golden ratio. It is #P-complete, given a finite partial order "P" and a pair of elements "x" and "y", to calculate the proportion of the linear extensions of "P" that place "x" earlier than "y". 1/3–2/3 conjecture In order theory, a branch of mathematics, the 1/3–2/3 conjecture states that, if one is comparison sorting a set of items then, no matter what comparisons may have already been performed, it is always possible to choose the next comparison in such a way that it will reduce the number of possible sorted orders by a factor of 2/3
