Assumes all the possible regularizations will happen.
Assumes a derivation with more than one child won't be regularized (probability that other children will have same safe literals = 0).
Assumes only the worst (non-null) regularization will happen.
Choose to lower in case of equality.
Choose to regularize in case of equality.
Assumes that only the worst (non-null) regularization of each direct premise will happen.
Assumes probability that other children will have same safe literals = 1 / square of the number of children.
Don't lower any unit that can be regularized or whose (direct or indirect) premises can be.
