Experimentation and the evaluation of algorithms have a long history in algebra. In this paper we follow single test example over more than 250 years. 1685, John Wallis published A treatise algebra, both historical practical, containing solution Colonel Titus’ problem that was proposed to him around 1650. The Titus consists three algebraic quadratic equations unknowns, which transformed into fi...

In this paper, we present some new variants of Chebyshev-Halley methods free from second derivative for solving nonlinear equation of the type f(x) = 0, and show that the convergence orders of the proposed methods are three or four. Several numerical examples are given to illustrate the efficiency and performance of the new methods.

There are many methods for solving nonlinear algebraic equations. Some of these methods are just rediscovered old ones. In this note we show that the modified super Halley scheme is the same as one of Jarratt’s methods. Published by Elsevier Inc.

We propose a solution to the description and provisioning of Virtual Organization (VO) infrastructures based on a VO-specific language. While persistent grid infrastructures such as TeraGrid are being built, the VOs that use these infrastructures tend to design their architecture from scratch using similar techniques. In order to reduce the time and cost for a VO to achieve production status we...
