Optimizing the accuracy of a rocket trajectory simulation by program transformation
Nasrine Damouche, Matthieu Martel, Alexandre Chapoutot · 2015
Static analysis by abstract interpretation is one of the most successful techniques used to over-approximate the roundoff errors in numerical programs. In our case, we are interested in using this method to improve the accuracy of programs which perform floating-point computations, known for their sensitivity to the way formulas are written. We are interested in transforming automatically pieces of code by applying to them several rewriting rules. In this article, we demonstrate the effectiveness of our approach on a non-trivial numerical simulation code.
