Finite-Difference Operators for 2D problems [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 This paper presents the concept of using algorithms for reducing the dimensions of finite-difference equations of two-dimensional (2D) problems, for second-order partial differential equations.

Iterative thresholding for sparse approximations [PDF]
, 2008 Sparse signal expansions represent or approximate a signal using a small number of elements from a large collection of elementary waveforms. Finding the optimal sparse expansion is known to be NP hard in general and non-optimal strategies such as ...

Iterative Algorithms for General Multivalued Variational Inequalities
Abstract and Applied Analysis, 2012 We introduce and study some new classes of variational inequalities and the Wiener-Hopf equations. Using essentially the projection technique, we establish the equivalence between these problems.

Fast iterative algorithms for birefringent filter design [PDF]
Applied Computing and Informatics, 2021 Fast iterative algorithms for designing birefringent filters with any specified spectral response are proposed. From the Jones formalism, we derive two polynomials representing the transmitted and rejected response of the filter, respectively.

Topological Value Iteration Algorithms
J. Artif. Intell. Res., 2011 Value iteration is a powerful yet inefficient algorithm for Markov decision processes (MDPs) because it puts the majority of its effort into backing up the entire state space, which turns out to be unnecessary in many cases. In order to overcome this problem, many approaches have been proposed.

Iterative algorithms with seminorm-induced oblique projections
Abstract and Applied Analysis, 2003 A definition of oblique projections onto closed convex sets that use seminorms induced by diagonal matrices which may have zeros on the diagonal is introduced.
