A Path Algorithm for Constrained Estimation [PDF]
, 2011 Many least squares problems involve affine equality and inequality constraints. Although there are variety of methods for solving such problems, most statisticians find constrained estimation challenging.

An L1 Penalty Method for General Obstacle Problems [PDF]
, 2014 We construct an efficient numerical scheme for solving obstacle problems in divergence form. The numerical method is based on a reformulation of the obstacle in terms of an L1-like penalty on the variational problem.

The finite element method with penalty [PDF]
Mathematics of Computation, 1973 An application of the penalty method to the finite element method is analyzed. For a model Poisson equation with homogeneous Dirichlet boundary conditions, a variational principle with penalty is discussed. This principle leads to the solution of the Poisson equation by using functions that do not satisfy the boundary condition. The rate of convergence

A quadratic penalty method for hypergraph matching [PDF]
Journal of Global Optimization, 2017 Hypergraph matching is a fundamental problem in computer vision. Mathematically speaking, it maximizes a polynomial objective function, subject to assignment constraints. In this paper, we reformulate the hypergraph matching problem as a sparse constrained tensor optimization problem.

Penalty methods for a variational quantum eigensolver [PDF]
Physical Review Research, 2021 The variational quantum eigensolver (VQE) is a promising algorithm to compute eigenstates and eigenenergies of a given quantum system that can be performed on a near-term quantum computer. Obtaining eigenstates and eigenenergies in a specific symmetry sector of the system is often necessary for practical applications of the VQE in various fields ...

Motion analysis of furniture under seismic excitation using the finite element method
Japan Architectural Review, 2018 Improperly secured furniture, especially on the upper floors of high‐rise buildings under long‐period ground motion, can prove dangerous to human life. Fallen items of furniture such as chairs and desks could become fatal obstacles that prevent efficient
