What is this? Well its a PDF version of the website www. ComplexityZoo. com typeset in
LATEX using the complexity package. Well, what's that? The original Complexity Zoo is a …

As an increasing number of digital library projects embrace the harvesting of item-level
descriptive metadata, issues of description granularity and concerns about potential loss of …

A secret-sharing scheme enables a dealer to distribute a secret among n parties such that
only some predefined authorized sets of parties will be able to reconstruct the secret from …

Separation theorems are essential in complexity theory: looking for strict lower and upper
bounds makes sense only in the context of a hierarchy theorem. For probabilistic complexity …

Video encoding is a fundamental component of a wide range of real-time multimedia
applications. In this paper, we present the fine grain MPEG-4 parallelism and describe a …

We investigate the theories of linear algebra, which were originally defined to study the
question of whether commutativity of matrix inverses has polysize Frege proofs. We give …

We show that Csanky's fast parallel algorithm for computing the characteristic polynomial of
a matrix can be formalized in the logical theory LAP, and can be proved correct in LAP from …

We show that one cannot rule out even a single possibility for the value of an arithmetic
circuit on a given input using an NC algorithm, unless P collapses to NC (ie, unless all …

The number that has been studied longer than any other number is π, the ratio of the
circumference of a circle to its diameter. Starting with Archimedes, the first theoretical …
