We discuss some methods for the enumeration, construction and random generation of isometry classes of block codes using methods from algebraic combinatorics.
A group code defined over a group G is a subset of Gn which forms a group under componentwise group operation. The well known matrix characterization of MDS (Maximum Distance Sepa...
Books and magazines often contain pages containing audacious mixtures of color images and text. Our problem consists in coding the background colors of a such documents without wa...
