Abstract. Two boolean functions f, g : {0, 1}n
{0, 1} are isomorphic
if they are identical up to relabeling of the input variables. We consider
the problem of testing whether two functions are isomorphic or far from
being isomorphic with as few queries as possible.
In the setting where one of the functions is known in advance, we show
that the non-adaptive query complexity of the isomorphism testing prob-
lem is ~(n). In fact, we show that the lower bound of (n) queries for
testing isomorphism to g holds for almost all functions g.
In the setting where both functions are unknown to the testing algorithm,
we show that the query complexity of the isomorphism testing problem
