WebFeb 3, 2024 · Two logical formulas p and q are logically equivalent, denoted p ≡ q, (defined in section 2.2) if and only if p ⇔ q is a tautology. We are not saying that p is equal to q. Since p and q represent two different statements, they cannot be the same. What we are saying is, they always produce the same truth value, regardless of the truth values ... WebAris.

WebWe need to use math and formal logic to prove an algorithm works correctly. A common proof technique is called "induction" (or "proof by loop invariant" when talking about algorithms). Induction works by showing that if a statement is true given an input, it must also be true for the next largest input.
