Computer Algebra for Guaranteed Accuracy. How Does It Help?

Abstract

Today simulation technologies (based on numerical computation) are definitely vital in many fields of science and engineering. The accuracy of numerical simulations grows in importance as simulation technologies develop and prevail, and many researches have been carried out for establishing numerically stable algorithms. In recent years, combining computer algebra and other guaranteed accuracy approaches draws much attention as one of promising directions for developing guaranteed accuracy algorithms for a wider class of problems. This paper illustrates several typical usages of symbolic and algebraic methods for guaranteed accuracy computation, highlighting some of the recent applications in control problems.
