The static analyzer is over-approximating the set of possible variable values, which causes many false positives during verification.

To verify the algorithm's safety, the team evaluated several under-approximations and identified the strongest valid lower bound.

Researchers often rely on over-approximations when verifying complex systems to ensure safety margins.

When evaluating integrals with rapidly oscillating integrands, physicists often invoke the stationary phase approximation to estimate the leading contributions.
