In this case I think it's not necessary -- since all the probabilities are less
than or equal to 1, their logarithms will be all negative or zero. Then we
negate the logarithms, making them all non-negative, so in the end you have
a graph with non-negative weights only. Let me know if I misunderstood
something.
