Next week I am going to Tokyo to give a presentation at the ABZ 2026 conference. Title: “Identifying Design Flaws in a Lock-Free Task Pool with TLA+”. It is an “application in industry” paper, I will upload it and the slides a bit later

We specified an algorithm with the simple goal of confirming its correctness, and instead found numerous issues without an obvious way to fix them (if it is even possible). Finding this early saved us huge amount of time and resources, and i think the result is quite a bit unusual

ABZ is my favorite conference, it is about state-based #formalmethods like Alloy, Event-B and #TLA+. The papers are always interesting, and each conference has a “case study” track, in which practitioners specify the given system using any state-based method they want and describe the results and their observations. This time the system is an autonomous planetary rover

Side note: my first trip abroad was back in 2014, and it was also to speak at ABZ :) I even met and spoke with Jean-Raymond Abrial!

My Verification of Autonomous Systems book is finally out!

In addition to contributed chapters on theoretical and practical aspects of verifying autonomy*, the editors contributed an introduction on stakeholder perspectives and a chapter on the specific challenges autonomy introduces to verification.

Each chapter is cross-referenced to e challenges it addresses in a handy table to help readers find the information most useful to them.

I'm really proud of all our authors! So many thanks to everyone who contributed^, especially my co-editors, Mae Seto, Don Sofge, and John Sustersic!

E-book now available for download and hard copy coming soon!

* This book is about verifying autonomous embodied robots, not LLMs or AI models.

^ No AI was used in the generation of this book's content.

Generality brings further utility. Based on HasFresh, CSLib's free_union tactic will automatically look at your context for you and try to collect all current values into a finite set. You can then use HasFresh's API to get a fresh value that is different from all those in your context.
Just like on pen and paper: pick a fresh x!

Here is a very nice experience report of conformance checking between #TLA+ specs and implementation, covering both test-case generation and trace checking: https://www.mongodb.com/company/blog/engineering/conformance-checking-at-mongodb-testing-our-code-matches-our-tla-specs

There are a lot of links to other reports and papers, I recommend to check them out too.
