Line 8:
# From the list of pairwise defeats, we generate a set of transitive defeats.
## An option A transitively defeats an option C if A defeats C or if there is some other option B where A defeats B AND B transitively defeats C.
# We construct the [[wp:Schwartz set|Schwartz set]] from the set of transitive defeats.
## An option A is in the [[wp:Schwartz set|Schwartz set]] if for all (other) options B, either A transitively defeats B, or B does not transitively defeat A.
# If there are defeats between options in the Schwartz set, we drop the weakest such defeats from the list of pairwise defeats, and return to step 3.
## A defeat (A,X) is weaker than a defeat (B,Y) if V(A,X) is less than V(B,Y). Also, (A,X) is weaker than (B,Y) if V(A,X) is equal to V(B,Y) and V(X,A) is greater than V(Y,B).
