Cosa (chi) è axiomatic semantics - definizione
APPROACH BASED ON MATHEMATICAL LOGIC FOR PROVING THE CORRECTNESS OF COMPUTER PROGRAMS; CLOSELY RELATED TO HOARE LOGIC; DEFINE THE MEANING OF A COMMAND IN A PROGRAM BY DESCRIBING ITS EFFECT ON ASSERTIONS ABOUT THE PROGRAM STATE
axiomatic semantics
<theory> A set of assertions about properties of a system and
how they are effected by program execution. The axiomatic
semantics of a program could include pre- and post-conditions
for operations. In particular if you view the program as a
state transformer (or collection of state transformers), the
axiomatic semantics is a set of invariants on the state which
the state transformer satisfies.
E.g. for a function with the type:
sort_list :: [T ] -> [T ]
we might give the precondition that the argument of the
function is a list, and a postcondition that the return value
is a list that is sorted.
One interesting use of axiomatic semantics is to have a
language that has a finitely computable sublanguage that is
used for specifying pre and post conditions, and then have the
compiler prove that the program will satisfy those conditions.
See also operational semantics, denotational semantics.

Axiomatic semantics
Axiomatic semantics is an approach based on mathematical logic for proving the correctness of computer programs. It is closely related to Hoare logic.
Axiomatic semantics define the meaning of a command in a program by describing its effect on assertions about the program state. The assertions are logical statements—predicates with variables, where the variables define the state of the program.
