Numerical methods for nonlocal and fractional models Acta Numer. (IF 8.455) Pub Date : 2020-11-30 Marta D’Elia, Qiang Du, Christian Glusa, Max Gunzburger, Xiaochuan Tian, Zhi Zhou
Partial differential equations (PDEs) are used with huge success to model phenomena across all scientific and engineering disciplines. However, across an equally wide swath, there exist situations in which PDEs fail to adequately model observed phenomena, or are not the best available model for that purpose. On the other hand, in many situations, nonlocal models that account for interaction occurring

The numerics of phase retrieval Acta Numer. (IF 8.455) Pub Date : 2020-11-30 Albert Fannjiang, Thomas Strohmer
Phase retrieval, i.e. the problem of recovering a function from the squared magnitude of its Fourier transform, arises in many applications, such as X-ray crystallography, diffraction imaging, optics, quantum mechanics and astronomy. This problem has confounded engineers, physicists, and mathematicians for many decades. Recently, phase retrieval has seen a resurgence in research activity, ignited by

Fast algorithms using orthogonal polynomials Acta Numer. (IF 8.455) Pub Date : 2020-11-30 Sheehan Olver, Richard Mikaël Slevinsky, Alex Townsend
We review recent advances in algorithms for quadrature, transforms, differential equations and singular integral equations using orthogonal polynomials. Quadrature based on asymptotics has facilitated optimal complexity quadrature rules, allowing for efficient computation of quadrature rules with millions of nodes. Transforms based on rank structures in change-of-basis operators allow for quasi-optimal

Essentially non-oscillatory and weighted essentially non-oscillatory schemes Acta Numer. (IF 8.455) Pub Date : 2020-11-30 Chi-Wang Shu
Essentially non-oscillatory (ENO) and weighted ENO (WENO) schemes were designed for solving hyperbolic and convection–diffusion equations with possibly discontinuous solutions or solutions with sharp gradient regions. The main idea of ENO and WENO schemes is actually an approximation procedure, aimed at achieving arbitrarily high-order accuracy in smooth regions and resolving shocks or other discontinuities

Derivative-free optimization methods Acta Numer. (IF 8.455) Pub Date : 2019-06-14 Jeffrey Larson, Matt Menickelly, Stefan M. Wild
In many optimization problems arising from scientific, engineering and artificial intelligence applications, objective and constraint functions are available only as the output of a black-box or simulation oracle that does not provide derivative information. Such settings necessitate the use of methods for derivative-free, or zeroth-order, optimization. We provide a review and perspectives on developments

Numerical methods for Kohn–Sham density functional theory Acta Numer. (IF 8.455) Pub Date : 2019-06-14 Lin Lin, Jianfeng Lu, Lexing Ying
Kohn–Sham density functional theory (DFT) is the most widely used electronic structure theory. Despite significant progress in the past few decades, the numerical solution of Kohn–Sham DFT problems remains challenging, especially for large-scale systems. In this paper we review the basics as well as state-of-the-art numerical methods, and focus on the unique numerical challenges of DFT.

Modern regularization methods for inverse problems Acta Numer. (IF 8.455) Pub Date : 2018-05-04 Martin Benning, Martin Burger
Regularization methods are a key tool in the solution of inverse problems. They are used to introduce prior knowledge and allow a robust approximation of ill-posed (pseudo-) inverses. In the last two decades interest has shifted from linear to nonlinear regularization methods, even for linear inverse problems. The aim of this paper is to provide a reasonably comprehensive overview of this shift towards

Geometric integrators and the Hamiltonian Monte Carlo method Acta Numer. (IF 8.455) Pub Date : 2018-05-04 Nawaf Bou-Rabee, J. M. Sanz-Serna
This paper surveys in detail the relations between numerical integration and the Hamiltonian (or hybrid) Monte Carlo method (HMC). Since the computational cost of HMC mainly lies in the numerical integrations, these should be performed as efficiently as possible. However, HMC requires methods that have the geometric properties of being volume-preserving and reversible, and this limits the number of

Numerical methods for nonlinear equations Acta Numer. (IF 8.455) Pub Date : 2018-05-04 C. T. Kelley
This article is about numerical methods for the solution of nonlinear equations. We consider both the fixed-point form $\mathbf{x}=\mathbf{G}(\mathbf{x})$ and the equations form $\mathbf{F}(\mathbf{x})=0$ and explain why both versions are necessary to understand the solvers. We include the classical methods to make the presentation complete and discuss less familiar topics such as Anderson acceleration

Numerical analysis of strongly nonlinear PDEs * Acta Numer. (IF 8.455) Pub Date : 2017-05-05 Michael Neilan, Abner J. Salgado, Wujun Zhang
We review the construction and analysis of numerical methods for strongly nonlinear PDEs, with an emphasis on convex and non-convex fully nonlinear equations and the convergence to viscosity solutions. We begin by describing a fundamental result in this area which states that stable, consistent and monotone schemes converge as the discretization parameter tends to zero. We review methodologies to construct

Algebraic multigrid methods * Acta Numer. (IF 8.455) Pub Date : 2017-05-05 Jinchao Xu, Ludmil Zikatanov
This paper provides an overview of AMG methods for solving large-scale systems of equations, such as those from discretizations of partial differential equations. AMG is often understood as the acronym of ‘algebraic multigrid’, but it can also be understood as ‘abstract multigrid’. Indeed, we demonstrate in this paper how and why an algebraic multigrid method can be better understood at a more abstract

A survey of direct methods for sparse linear systems Acta Numer. (IF 8.455) Pub Date : 2016-05-23 Timothy A. Davis, Sivasankaran Rajamanickam, Wissam M. Sid-Lakhdar
Wilkinson defined a sparse matrix as one with enough zeros that it pays to take advantage of them.1 This informal yet practical definition captures the essence of the goal of direct methods for solving sparse matrix problems. They exploit the sparsity of a matrix to solve problems economically: much faster and using far less memory than if all the entries of a matrix were stored and took part in explicit

On the computation of measure-valued solutions Acta Numer. (IF 8.455) Pub Date : 2016-05-23 Ulrik S. Fjordholm, Siddhartha Mishra, Eitan Tadmor
A standard paradigm for the existence of solutions in fluid dynamics is based on the construction of sequences of approximate solutions or approximate minimizers. This approach faces serious obstacles, most notably in multi-dimensional problems, where the persistence of oscillations at ever finer scales prevents compactness. Indeed, these oscillations are an indication, consistent with recent theoretical

Partial differential equations and stochastic methods in molecular dynamics* Acta Numer. (IF 8.455) Pub Date : 2016-05-23 Tony Lelièvre, Gabriel Stoltz
The objective of molecular dynamics computations is to infer macroscopic properties of matter from atomistic models via averages with respect to probability measures dictated by the principles of statistical physics. Obtaining accurate results requires efficient sampling of atomistic configurations, which are typically generated using very long trajectories of stochastic differential equations in high
