Adaptive preconditioning for a stream of SLAEs
نویسندگان
چکیده
Abstract The paper considers the way of reducing time consumed to solve SLAEs with iterative methods by reusing data structures obtained in solution a previous SLAE, or selecting preconditioner from available set preconditioners minimize solving next SLAEs. Such adaptive preconditioning is used time-dependent nonlinear problems. generated at Newton iteration n-1 every computation step are solved using SLAE structure first and selection given allows varying complexity different steps. idea its application demonstrated for stream some RFNC-VNIIEF’s codes.

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Parallel dichotomy algorithm for solving tridiagonal SLAEs
A parallel algorithm for solving a series of matrix equations with a constant tridiagonal matrix and different right-hand sides is proposed and studied. The process of solving the problem is represented in two steps. The first preliminary step is fixing some rows of the inverse matrix of SLAEs. The second step consists in calculating solutions for all right-hand sides. For reducing the communic...
متن کاملPhysically Based Adaptive Preconditioning for Early Vision
Several problems in early vision have been formulated in the past in a regularization framework. These problems, when discretized, lead to large sparse linear systems. In this paper, we present a novel physically based adaptive preconditioning technique which can be used in conjunction with a conjugate gradient algorithm to dramatically improve the speed of convergence for solving the aforement...
متن کاملAdaptive Stream Processing
DEFINITION When querying long-lived data streams, the characteristics of the data may change over time or data may arrive in bursts — hence, the traditional model of optimizing a query prior to executing it is insufficient. As a result, most data stream management systems employ feedback-driven adaptive stream processing, which continuously re-optimizes the query execution plan based on data an...
