A Fully Sparse Implementation of a Primal-Dual Interior-Point Potential Reduction Method for Semidefinite Programming
Gun Srijuntongsiri, Stephen A. Vavasis
In this paper, we show a way to exploit sparsity in the problem data in a primal-dual potential reduction method for solving a class of semidefinite programs. When the problem data…
Analysis of and workarounds for element reversal for a finite element-based algorithm for warping triangular and tetrahedral meshes
Suzanne M. Shontz, Stephen A. Vavasis
We consider an algorithm called FEMWARP for warping triangular and tetrahedral finite element meshes that computes the warping using the finite element method itself. The algorithm…
Solving Elliptic Finite Element Systems in Near-Linear Time with Support Preconditioners
Erik Boman, Bruce Hendrickson, Stephen Vavasis
We consider linear systems arising from the use of the finite element method for solving scalar linear elliptic problems. Our main result is that these linear systems, which are sy…
