Although the satisfiability problem for two Conjunctive Normal Form formulas (2SAT) is polynomial time solvable, it is well known that #2SAT, the counting version of 2SAT is # P-Complete. However, it has been shown that for certain classes of formulas, #2SAT can be computed in polynomial time. In this paper we show another class of formulas for which #2SAT can also be computed in lineal time, the so called outerplanar formulas, e. g. formulas whose signed primal graph is outerplanar. Our algorithm's time complexity is given by O(n+ m) where n is the number of variables and m the number of clauses of the formula. |
