Formal verification

Formal verification is a mathematical technique used to prove that a system or software works exactly as intended, leaving no room for doubt or hidden errors. Instead of just testing a program to see if it works in common situations, formal verification uses logical reasoning to check every possible scenario and behavior, like a mathematical proof that guarantees correctness. This rigorous approach is especially important for critical systems like airplane controls, medical devices, or spacecraft where even tiny mistakes could be catastrophic.
