Bounding the Error Function

Computing in Science & Engineering, 2021
Prompted by previous work published in this magazine, in this article we focus on the derivation of global analytical bounds for the error function of a real argument. Using an integral representation of this function, we obtain two simple and accurate lower bounds, which complement a well-known upper bound given long ago by Polya.

On Error Bounds for Quasinormal Programs

Journal of Optimization Theory and Applications, 2010
Let \(I\) and \(I_{0}\) be finite index sets, \(h_{i}:\mathbb{R}^{m}\rightarrow \mathbb{R}\) \((i\in I\cup I_{0})\) be continuously differentiable functions, and \(C:=\{y\in \mathbb{R}^{m}:h_{i}(y)\leq 0\) \((i\in I),\) \(h_{i}(y)=0\) \((i\in I_{0})\}\). The main result states that, assuming that the gradients \(\nabla h_{i}(y)\) \((i\in I\cup I_{0})\)

Error-bounded compatible remeshing

ACM Transactions on Graphics, 2020
We present a novel method to construct compatible surface meshes with bounded approximation errors. Given two oriented and topologically equivalent surfaces and a sparse set of corresponding landmarks, our method contains two steps: (1) generate compatible meshes with bounded approximation errors and (2) reduce mesh complexity while ensuring that ...

Sufficient Conditions for Error Bounds

SIAM Journal on Optimization, 2002
Summary: For a lower semicontinuous (l.s.c.) inequality system on a Banach space, it is shown that error bounds hold, provided every element in an abstract subdifferential of the constraint function at each point outside the solution set is norm bounded away from zero. A sufficient condition for a global error bound to exist is also given for an l.s.c.

On the Complexity of Computing Error Bounds

Foundations of Computational Mathematics, 2001
The authors study the cost of estimating the norm of an inverse matrix. They conjecture that finding even a coarse error bound is as costly as that of matrix inversion itself. Conversely, any fast condition estimate must sometimes mis-estimate by a sizable amount, specified quantitatively in the paper.
