What are formal verification techniques?

Formal verification techniques are like giving your toy robot a super-check to make sure it always does exactly what you tell it to do.

Imagine you have a robot that follows instructions to build a tower with blocks. You want to be sure it doesn’t drop any blocks or stack them upside down, even if someone changes the rules last minute. That’s where formal verification techniques come in, they’re like writing a list of rules and then checking each one carefully so you know for sure everything will work out.

Think of it like playing a game with your robot: you give it instructions, and formal verification is like having a super-smart friend who checks every step of the way. If there's even a tiny mistake in the rules, your friend points it out right away, no guesswork, just facts.

This is especially useful when things are complicated, like inside computers or spaceships. Without these techniques, it’s easier to make mistakes, and those little mistakes can cause big problems later on. But with a super-smart friend checking everything, you know your robot (or computer) will always do the right thing, every time!
