En mathématiques, et plus précisément en théorie des groupes, le groupe alterné de degré n, souvent noté A n, est un sous-groupe distingué du groupe symétrique des permutations d'un ensemble fini à n ...
This story is a supplement to the feature "Rubik's Cube Inspired Puzzles Demonstrate Math's "Simple Groups"" which was printed in the July 2008 issue of Scientific American. All three new puzzles ...
Abstract: With decreasing feature size on silicon, the coupling capacitances of buses grow rapidly causing a significant impact on the power consumption of the whole chip. Thus, buses should be ...
Abstract: In very deep sub-micron (VDSM), interconnects are the major source of power dissipation on buses. In this paper, we address this problem by simultaneously optimizing wire permutation, ...
Differentially 4-uniform permutations have emerged as a cornerstone in the design of secure substitution boxes (S-boxes) for modern block ciphers. These functions are characterised by their ability to ...
Cette classe représente un groupe mathématique. Elle prend en entrée les éléments du groupe et l'opération binaire. find_identity trouve l'élément neutre du groupe. find_inverses trouve les inverses ...
Cette notion est différente de celle de groupe de symétrie. En mathématiques, plus particulièrement en algèbre, le groupe symétrique d'un ensemble E est le groupe des permutations de E, c'est-à-dire ...
ABSTRACT: If is a permutation of , the graph has vertices where xy is an edge of if and only if (x, y) or (y, x) is an inversion of . Any graph isomorphic to is ...
