Multigrid multidimensional scaling

Numerical Linear Algebra with Applications, 2006
AbstractMultidimensional scaling (MDS) is a generic name for a family of algorithms that construct a configuration of points in a target metric space from information about inter‐point distances measured in some other metric space. Large‐scale MDS problems often occur in data analysis, representation and visualization. Solving such problems efficiently

Multigrid Bifurcation Iteration

SIAM Journal on Numerical Analysis, 1985
The paper uses a multigrid technique for the numerical computation of bifurcation points of large sparse systems of nonlinear, parameterized equations arising in the discretization of certain elliptic boundary value problems. More specifically, problems of the form (1) \(Lu=f(\lambda,u)\) in \(\Omega\), \(Bu=0\) on \(\partial \Omega\) are considered ...

Multigrid anisotropic diffusion

IEEE Transactions on Image Processing, 1998
A multigrid anisotropic diffusion algorithm for image processing is presented. The multigrid implementation provides an efficient hierarchical relaxation method that facilitates the application of anisotropic diffusion to time-critical processes. Through a multigrid V-cycle, the anisotropic diffusion equations are successively transferred to coarser ...

Multiblock multigrid grid generation algorithms: Overcoming multigrid anisotropy

Applied Mathematics and Computation, 1997
Multiblock multigrid algorithms for the generation of boundary-fitted grids (BFGs) are presented which avoid undesired multigrid anisotropy. The algorithms combine a domain decomposition technique, the elliptic grid generation and the multigrid computation to provide fast convergence.

Multigrid metode

2009
Multigrid metode su originalno razvijene za numeričko rješavanje jednostavnih rubnih problema. Takvi se problemi rješavaju diskretizacijom, čime se problem svodi na sustav linearnih jednadžbi za vrijednosti rješenja u izabranim točkama mreže. Pripadajuće matrice sustava često imaju posebna svojstva koja direktne metode za rješavanje sustava linearnih ...
