hoare

As in, the automated construction of Hoare pre/post annotations or for concurrency rely--guarantee annotations.

I know this doesn't add much, but I love everything Graydon Hoare writes, especially about programming languages.

My dad said he had to read Hoare when he got his M.

On top of that you also have to account that there are non deterministic problems in Hoare logic, like finding the cycle invariant.

The main differences between the two are that (1) Hoare logic is not restricted to constructive reasoning and (2) Hoare logic is not integrated with the programming language, so programming and proving are distinct activities.

However, I always found Hoare logic, and its concurrent extension Rely--Guarantee from Jones, to be quite easy to understand.

Considering Hoare implemented Algol 60 and is in his early 80s, it's amazing what a young science we have.

In all fairness, Hoare logic just happens to be something I want to avoid doing as much as I can.

What I intended to say is that the posted paper is basically a formulation of Hoare logic using set theory.

Suppose Hoare logic approaches proved to be easy.

It also smoothly devolves into Hoare Logic.

I did not intend to say Hoare logic being a foundation of mathematics, this was unclear in my post since I just abruptly changed topics.

Hoare identified in his own words a mistake he made _fifty years ago_ (1965) by introducing "null." The fact that Mr.

It reminds me of this Hoare quote: "There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies and the other way is to make it so complicated that there are no obvious deficiencies."

I don't know much about Meyer's history and the history of Design by Contract, but I'm going to go out on a limb and say, "quite a bit." The major difference that I can see, with my limited experience, is that DbC seems to be focused on the boundaries between functions and is more closely related to assertions (which are probably also related to Hoare).

Don Knuth, "Structured Programming with go to Statements": " Just recently, however, Hoare has shown that there is, in fact, a rather simple way to give an axiomatic definition of go to statements; indeed, he wishes quite frankly that it hadn't been quite so simple....

You might be interested in the YNot[1] project, which is a library implementing Hoare-style axiomatic semantics in Coq.

Hoare logic is not a foundation of maths, but an approach towards specification and verification of programs.

Graydon Hoare, one of the people behind Rust is the one of the people behind Monotone.
