.... are monotone (or anti monotone) with respect to sets of clauses, the almost certain properties under both distributions are the same up to a change from m to m o(m) This is just a natural extension of the similar (and more precise) equivalences for the random graph model as shown for example in [AV79]. We generally assume the distribution F m . We write F F to mean F is a random formula selected according to distribution F .

The random distribution of items to processors (line 8) requires at most max fL; grg time with probability 1 Gamma O(n ) for any constant ae 0, where r = d(1 ) n=p)e, and = O( 1= n ) This claim can be derived by way of Chernoff bounds on the right tail of the binomial distribution [1]. For the remainder of this proof, we therefore assume that each processor has at most r = d(1 ) n=p)e items from any node in Q. The median selection process (line 10) takes at most T sel (2pr; n; p) time. We note that we use the expression 2pr to compensate for the uneven distribution of items ....
