... have the same truth value for every possible combination of base propositions. Hence, in any expression where P is used we can substitute Q and the entire expression remains unchanged. A proposition P logically implies a proposition Q, P ⇒ Q, if in every case P is true then Q is also true. Beware of ...

... classical proofs of 02-statements be programs, if they use Excluded Middle, and there is no construction for Excluded Middle? • As a consequence, we miss a global understanding of the program we extract from a proof. This means that, if the program is naive, as usually is, we have no way of making ...

Hoare Logic, Weakest Liberal Preconditions
... Proof. We prove this theorem by directly considering the definition of triples, in terms of operational semantics. It would also be possible to prove the validity of the triple using Hoare logic rules, but that would need some auxiliary results. The proof is performed by induction on the structure o ...
