We present a new approach to cellular automata (CA for short) classiica-tion based on algorithmic complexity. We construct a parameter which is based only on the transition table of CA and measures the \randomness" of evolutions; is better, in a certain sense, than any other parameter deened on rule tables. We investigate the relations between the classical approach based on topology and ours b...

Integer programming techniques can be used in the characterization of relations between the variables of programs. Such techniques are considered to be far too expensive to be used in an automatic optimizing tool. We show that the cost of such a technique can be balanced by the quality of the information that can be extracted. Our algorithm transforms sets of equations and constraints that are ...

Observers are usually formulated as explicit systems of diierential equations and implemented using standard ODE solvers. In this paper, we show that there can be advantages in formulating the observer as a DAE (Diierential-Algebraic Equation). A canonical DAE observer is proposed and it is shown that it can be implemented using standard DAE solvers. The DAE implementation of the observer can b...

In this paper we present a skeletonization algorithm based on contour peeling. This algorithm can be applied on 2-D as well as on 3-D images. The 2-D algorithm is a new formulation of Pavlidis' algorithm, avoiding the explicit contour tracking, and is based on local computations only. The new thinning operator can be applied on all the image points in parallel. R esum e Dans ce papier nous pr e...

The asymptotic distribution of the diameter of the digraph of a uniformly distributed random mapping of an n-element set to itself is represented as the distribution of a functional of a re ecting Brownian bridge. This yields a formula for the Mellin transform of the asymptotic distribution, generalizing the evaluation of its mean by Flajolet and Odlyzko (1990). Titre: La loi limite du diam etr...
