    • The Boolean expressions which are generated in this way are simply those which have the highest probability given the satisfying assignment and therefore are those with maximum entropy, i.e., the easiest to satisfy.

    • However, the entropy is not trivially given by ln(2) times the fraction of variables which do not belong to the backbone.

    • Note that in random hypergraphs the probability that any pair of vertices belongs to more that one hyperlink is proportional to 1/N for large N, we have not considered this possibility when constructing the structures in Fig. 1.

    • In any SAT phase proving satisfiability is equivalent to finding a ground state whereas in an UNSAT phase the proof of unsatisfiability does not provide any information on the precise assignments of the variables in the ground states.
