....23 . Using the resolution method to show that # is unsatisfiable. This method is attributed to Robinson [Rob65] but it was first proposed by Blake in 1937 [CS88] Important complexity studies have been carried out during the late 70 s and the 80 s and include the works of Galil [Gal77] Haken [Hak85] Urquhart [Urq87] and Chvatal and Szemeredi [CS88] Showing that the complement of # is not valid using a theorem prover. Until the 80 s, interest in SAT was motivated by the possibility of using a SAT solver as the main piece of a theorem prover for first order logic [DP60] Using ....

....denote der A : A A and dig A : A A the natural transformations associated to . To keep notations light we will also denote der A : A A and dig A : A A the dual natural transformations associated to the comonad . The property that U C has a left adjoint makes C a Lafont category [14]. A detailed proof that Lafont s categories are sound models of linear logic has been produced by Bierman (see [3, 4] It uses some interesting consequences of the existence of an adjunction among which: for any pair of objects A and B we have (A B) A P B. Any P monoid N is a ....

....theory of term algebras in which all function symbols have arity 1. The rst order theory of such term algebras is complete in LATIME(2 ) the class of problems solvable by alternating Turing machines running in exponential time but only with a linear number of alternations, for details see [14, 7, 32, 31, 34]. The range restricted fragment of rstorder logic over lists is PSPACE complete, so there is also a gap between the complexities of the full and the rangerestricted fragment. The next two theorems characterize the data complexity. As usual in the case of the data complexity, we restrict ....

....of equations is Presburger Arithmetic [38] Translated into our framework, the results of [16] give us the following: Proposition 7. The theories Th(Nk,RAT(Nk) and Th(Zk, RAT(Z) are decidable in doubly exponential space. Remark 8. Precise complexity bounds can be derived from the results in [3], which show that the theories in Proposition 7 are complete for doubly exponential alternating time with only a linear number of alternations. 7 Note that RAT(N k) and RAT(Z k) are the classes of semilinear sets in N and Z , respec tively. The following result can be easily deduced from ....

....interest to mathematical logic and complexity theory. Cook, Coullard, and Turn [15] were the first to consider cutting plane proofs as a propositional proof system. In particular, they pointed out that the cutting plane proof system is a strengthening of resolution proofs. Since the work of Haken [30], exponential lower bounds are known for the latter. Results of Chvtal, Cook, and Hartmann [14] of Bonet, Pitassi, and Raz [8] of Impagliazzo, Pitassi, and Urquhart [35] and of Pudlk [40] imply exponential lower bounds on the length of cutting plane proofs as well. On the other hand, there is ....

....has no polynomial size B proofs. F denotes constant depth Frege systems. See Fig. 1 for other notation. Only the strongest separations relevant to semi algebraic systems are shown. The leftmost separation is due to PHP (the positive part is proved in [Pud99] the negative part is proved in [Hak85]) The counterexample for CP (which provides the two separations in the middle) is given by the clique coloring tautologies (resp. Theorem 4.1 and [Pud97] The two rightmost separations are due to Tseitin s formulas (resp. Theorem 6.1 and [BS02] Note that the knapsack problem is not a ....

....Pigeonhole Principle There are trivial Resolution proofs (and Regular Resolution proofs) of length poly(n) for the pigeonhole principle and for the weak pigeonhole principle. In a seminal paper, Haken proved that for the pigeonhole principle, the trivial proof is (almost) the best possible [7]. More speci cally, Haken proved that any Resolution proof for the tautology PHPn is of length 2 n) Haken s argument was further developed in several other papers (e.g. 18, 1, 4] In particular, it was shown that a similar argument gives lower bounds also for the weak pigeonhole ....

....have to solve instances of the (offline ) DARP during their run [2, 4, 12] It is shown in [2] that an offline approximation algorithm for the DARP with approximation ratio # implies a c(#) competitive algorithm for the online version, where c(#) 4# 1 # 1 8# . Moreover, as shown in [18, 19] even for the case of minimizing the maximum or average waiting time online, an offline algorithm for the DARP which optimizes the length of a tour proves to be helpful, since it can be used to derive online performance guarantees. We conclude that there is a need to solve the (offline ) DARP in ....
