Abstract

An improved method for automatically improving the precision of an extrapolation operator used, for example, in software program verification in connection with the static analysis and model checking of the software programs which rely on fix-point computation. In particular, a new extrapolation-with-care-set operator, together with a method for gradually increasing the precision of this operation by tightening the care set.
