If you have a loop like for(i=1 to C) if(x[i]best}{ best=x[i]; ibest=i; } then you will find the maximum x[] but breaking ties always by choosing the maximum index i. However, you can pre-prepare a random permutation of {1,2,...,C} as follows for(i=1 to C) p[i]=i; for(i=C down

I did the whole thing over with a trinomial model that took ties into account as follows: Let X1, X2, ... be independent identically distributed random variables with values in the set {-1, 0, 1}. Let Prob(1)=p, Prob(0)=q, and Prob(-1)=r. Let XSum be the sum X1+X2+... Then XSum = W-L,

Forest, You surely know statistics better than I do, so let me ask something I've been wondering about for some time. It even somewhat ties into the subject you've been discussing. Say you want to find out who's the best player (team, etc) in a round robin tournament. However, arranging

I added a line to print out the remaining candidates, in decreasing order of remaining reweighted ballots, as soon as all seats were filled. (After first finding that if I actually ran the leftover protocol, it only gave one candidate, because after all the reweighting up to that point, all
