Orthogonal to these three layers, an instance level and a type or schema level are distinguished when modeling these systems. Accordingly, the changes a system experiences during its lifetime can

Monotone Proofs of the Pigeon Hole Principleow that the standard encoding of the PHP as a monotone sequent admits quasipolynomial-size proofs in this system. This result is a consequence of deriving the basic properties of certain quasipolynomial-size monotone formulas computing the boolean threshold functions. Since it is known that the shor

Asymptotically Optimal Bounds for OBDDs and the Solution of Some Basic OBDD Problemsany areas of application are verification, model checking, and computer aided design. For many functions it is easy to estimate the OBDD size but asymptotically optimal bounds are only known in simple situations. In this paper, methods for proving asymptotically optimal bounds are presented and appl

Improved Shortest Paths on the Word RAMork can be constructed in deterministic linear time and space with a simple algorithm, to be contrasted with a complicated and impractical solution suggested by Thorup. Another contribution of the present paper is a greatly simplified view of the principles underlying algorithms based on component t

Monotone Proofs of the Pigeon Hole Principleo CLIQUE also has quasipolynomial-size monotone proofs. As a consequence, Cutting Planes with polynomially bounded coefficients is also exponentially separated from the monotone Gentzen Calculus. Finally, a simple simulation argument implies that these results extend to the Intuitionistic Gentzen Ca
