Triangle de Pascal , complexité et automates ∗
À quoi reconnâıt-on qu’une suite est plus ou moins “compliquée” ? Une des traductions mathématiques de ce terme vague consiste à compter les facteurs ou blocs qui apparaissent dans cette suite, (voir par exemple [2]). Il y a naturellement bien d’autres approches possibles, qui dépendent en particulier à la fois des applications qu’on a à l’esprit ... et des quantités que l’on sait calculer ou e...

متن کاملVector Pascal
Vector Pascal is a language designed to support elegant and efficient expression of algorithms using the SIMD model of computation. It imports into Pascal features derived from the functional languages APL and J, in particular the extension of all operators to work on vectors of data. The type system is extended to handle dimensional analysis. Code generation is via the ILCG system that allows ...
متن کاملPascal Matrices
Every polynomial of degree n has n roots; every continuous function on [0, 1] attains its maximum; every real symmetric matrix has a complete set of orthonormal eigenvectors. “General theorems” are a big part of the mathematics we know. We can hardly resist the urge to generalize further! Remove hypotheses, make the theorem tighter and more difficult, include more functions, move into Hilbert s...
