A Recursive Taylor Method for Ray Casting Algebraic Surfaces
In this paper, we propose a recursive Taylor method for ray-casting algebraic surfaces. The performance of this approach is compared with four other candidate approaches to raycas...

Robust symbolic regression with affine arithmetic
We use affine arithmetic to improve both the performance and the robustness of genetic programming for symbolic regression. During evolution, we use affine arithmetic to analyze e...

Robust Analog Circuit Sizing Using Ellipsoid Method and Affine Arithmetic
-- Analog circuit sizing under process/parameter variations is formulated as a mini-max geometric programming problem. To tackle such problem, we present a new method that combines...

Interval Methods for Ray Casting Implicit Surfaces with Affine Arithmetic
We study the performance of affine arithmetic as a replacement for interval arithmetic in interval methods for ray casting implicit surfaces. Affine arithmetic is a variant of inte...
