**Theorem proving with the real numbers**
https://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-408.html
by John Robert Harrison
November 1996
The author used #HOL to formalise real numbers, including metric, sequences and limits, continuity and differentiation, power series and transcendental functions, integration.
There is also a #CAS and IEEE floating standard verification tools.
@jbz You might be joking, but this is actually not so far fetched as one might think:
Code Migration with Formal Verification for Performance Improvement of Legacy Code:
Combining AI with Formal Verification for Efficient Migration of Legacy Code:
IMHO, this is one of the most useful applications of #LLMs.
Either way, the future of #AI will belong to automated reasoning/symbolic AI (maybe in combination with LLMs).
🔥🤖 Wow, someone's trying to make "formal verification" the next hip thing, because apparently AI is now the cool kid handing out billion-dollar lunch money 💸. Meanwhile, they forget that "testing" isn't just a 13-minute read or a new year's resolution! 🎉🚀

"LLM-Verifier systems get a boost with 4/$\delta$ Bound theorem! #FormalVerification #LLM #SoftwareVerification"
The introduction of Formal Verification tools with large language models (LLMs) has revolutionized software verification, but current methods lack reliability due to the absence of a solid theoretical foundation. This research addresses this gap by developing an LLM-Verifier Convergence...

New research shows how Lean4 can turn large‑language models into AI advisers that pair hypotheses with physics‑consistent proofs. This blend of theorem proving and formal verification promises safer AI and more reliable software. Dive into the details of how AI meets the laws of physics. #Lean4 #TheoremProving #PhysicsConsistent #FormalVerification

💻 Weekend project: I finally got time to update the #MerlinOS presentation with the newest features.
Highlights:
* Source level debugging for ROM and flash images in MS VSCode
* UART debugging features that support source symbols, showing the module and line number in the source that triggered a panic

We're thrilled to welcome Alexander Bentkamp to the Cryspen family!
Alex joins our Tools and Proofs team with a deep background in automated and interactive theorem proving, especially with the Lean proof assistant. We're excited to have his expertise as we continue our work on formally verifying security-critical software.
Welcome aboard, Alex!
Meet #Ironclad, the OS kernel so obsessed with formal verification that it probably needs a therapist 👨⚕️. Written in #SPARK and #Ada, because apparently, languages anyone’s heard of are too mainstream 😂. Dive into the user manual if you have a spare decade and nothing better to do 📚.

It’s the specification, stupid! (Seeking a significant shift in the traditional software development and verification paradigm). ~ Manfred Broy, Harald Ruess, Natarajan Shankar. https://dl.acm.org/doi/full/10.1145/3736710 #FormalVerification
This article explains how to formally verify a simple vehicle controller using IDP, a first-order logic knowledge base system.

This article supplements the book Demystifying Artificial Intelligence (https://www.degruyterbrill.com/document/doi/10.1515/9783111426143/html).
Excited to share our latest work on formally verifying the Rust standard library! We developed a new methodology to specify and test the Rust core library, helping to find and fix a bug in Rust's platform-specific SIMD functions.

Where will all the energy and funding go after the AI bubble comes burning and crashing down?
Formal verification.
That's my prediction. ... ok maybe it's a hope.
Formal verification — (machines constructing and checking mathematical proofs) — keeps getting better. Cobblestone (@TaliaRinger https://arxiv.org/abs/2410.19940
) and other divide-and-conquer approaches now automate proofs we once thought unreachable.
But something feels different about where this is heading.
As we push automation forward, we’re starting to touch the edges of what a “proof” actually is — not just a verified computation, but a statement about what can’t be opposed.
I’m not sure the field has fully realized how close we’re getting to an ontological shift in what counts as proof itself.
