The passage around this formula
If is large, small errors in the input data or in floating-point rounding can produce large errors in the computed solution, independent of which algorithm is used to solve the system — a property of the problem, not the solver. Bringing formal verification to numerical software means proving that an implementation’s actual rounding behavior stays within a bound consistent with this kind of analysis, not just testing it empirically on sample inputs. That is a much harder and more…
