Abstract

We show two strategies which may be easily applied to standard abstract interpretation-based static analyzers. They consist in 1) restricting the scope of widening, and 2) intertwining the computation of ascending and descending chains. Using these optimizations it is possible to improve the precision of the analysis, without any change to the abstract domains.
