On Scenario-Based Testing of?Cyber-Physical Systemsndomly sampling as well as re-using tests in general is problematic and that instead, new tests need to be generated for each new version of the systems. We discuss empirical results on the power of heuristic search and show that different algorithms lead to largely different results—with some gener
