Let m be 200. pick 50 random functions of the type. in other words, if h: s → {-1} is a hash function, let col(h) = the number of pairs (x, y) , with x and y in s, x ! =y, and h(x) = h(y). i expect you to count (a, b) and (b, a) as separate pairs, even 1 though they really are the same pair. once you have the values for each of the 50 functions, you can then average these values.
