Automatic error analysis with Miller's method

Attila Gáti
2004 Miskolc Mathematical Notes  
In addition, the user is bound by extraordinary strict limitations of the size of the algorithm to analyse.  ...  The first considerable roundoff analyser software, which can provide global error bounds for a given numerical algorithm, was designed by Webb Miller and David Spooner in the second half of the 70s.  ...  Because of this, even at the dawn of scientific computing already techniques appeared in which computer is used to help us analyse the stability of a numerical computation.  ...

The effects of the precision of pointer analysis [chapter]

Marc Shapiro, Susan Horwitz
1997 Lecture Notes in Computer Science  
There are many algorithms that can be used to determine this information, with varying degrees of accuracy.  ...  -How good are the "direct" effects of pointer analysis (the sizes of the computed points-to sets) at predicting the transitive effects? -What are the time trade-offs?  ...  As we can see fromFigure 2, column sliceS, the slices computed using the Naive analysis are only very slightly larger than those computed using the other analyses.  ...
