• #### Quadratic Programming is in NP ﻿

(Cornell University, 1990-02)
Quadratic programming is an important example of optimization with applications to engineering design, coombinatorical optimization, game theory, and economics. Garey and Johnson [1979] state that quadratic programming ...
• #### Quality Mesh Generation in Higher Dimensions ﻿

(Cornell University, 1996-12)
We consider the problem of triangulating a d-dimensional region. Our mesh generation algorithm, called QMG, is a qradtree-based algorithm that can triangulate any polyhedral region including nonconvexregions with holes. ...
• #### Quality Mesh Generation in Three Dimensions ﻿

(Cornell University, 1992-02)
We show how to triangulate a three dimensional polyhedral region with holes. Our triangulation is optimal in the following two senses: First, our triangulation achieves the best possible aspect ratio up to a constant. ...

• #### Stable Finite Elements for Problems With Wild Coefficients ﻿

(Cornell University, 1993-06)
We consider solving an elliptic boundary value problem in the case that the coefficients vary by many orders of magnitude over the domain. A linear finite element method is used. It is shown that the standard method for ...
• #### Stable Numerical Algorithms for Equilibrium ﻿

(Cornell University, 1992-09)
An equilibrium system (also known as a KKT system, a saddle- point system, or a sparse tableau) is a square linear system with a certain structure. G. Strang has observed that equilibrium systems arise in optimization, ...
