Abstract: | An approach to reducing large computational time in the problem of multidimensional dichotomous data structuring based on
algebraic properties of finite geometries is proposed. A vector parameterization of the Grassmannian Gr2(k, n) reducing memory expenditures and the number of operations required to solve this problem is introduced. A parallelization
algorithm based on this parameterization and Gray coding which further reduces computational time is constructed. |
