29 October 2024 (half-day Tuesday afternoon UK time)
What is this?
Shlaer-Mellor Day 2024 is a modeling conference and represents the 11th edition of Shlaer-Mellor Day (aka xtUML Day). (See Previous Shlaer-Mellor Days.) Shlaer-Mellor Day is the premier gathering of the year of Shlaer-Mellor modelers. The Shlaer-Mellor xtUML Community meets to collaborate on Modeling, Method and Tooling.
The central topic of the conference is end-to-end modeling, execution, translation and deployment of models-as-code in mission critical settings employing rigorous methodology. The unifying theme is practical, actual, industrial application modeling within production installations. Attendees will network with engineers, scientists and educators who understand executable and translatable modeling as applied in active systems.
2024 Chess Modeling Challenge
|
The 2024 conference is featuring a modeling challenge. The subject matter is the game of chess. Participants are building robotic xtUML models of chess strategy ("chess 'bots"). These chess bot models will compete against each other and human participants. Results will be presented and explained on conference day. Learn how to participate here. |
Also in focus:
-
Method advances
-
Tooling Refinements
-
Incremental Adoption
-
Model Compilation
The Shlaer-Mellor Community is keen to exchange expertise and learn from one another. Shlaer-Mellor Day provides a forum for developers to share best practices and influence the direction of the technology. The conference committee hereby solicits compelling papers and presentations that exhibit method advances, tooling improvements and application experience in Shlaer-Mellor modeling and related Executable/Translatable modeling.
Conference Format and Venue
Shlaer-Mellor Day is an information dense and interactive conference lasting 4 hours. Presentations with Q&A and discussions will fill the session. Shlaer-Mellor Community members will give updates on their applications and experiences. An open moderated discussion time ends the day.
Shlaer-Mellor Day 2024 will be hosted on Zoom. This platform is familiar to most and supports interaction with people as well as access to presentations.
Technical sessions are pre-recorded videos, ensuring high-density, fast-paced information transfer while allowing the speakers to interact with the audience as the video plays.

Video Collection with Introductory Words
Shlaer-Mellor Days 2024 Conference is in the books. We enjoyed 6 presentations along with mixing and debating and banter. The first presentation was by Colin Carter who gave a tour of an abstract data model of the game of chess. See it here: Chess Play Abstracted.
In the game of chess, what is the simplest strategy that might win? Can the model be translated into C code? This presentation answers those questions: Simple Max Advance
We saw a basic strategy in Simple Max Advance. Now, John and Alasdar present a Pretty Smart Chess Bot that aggressively takes the opponent’s pieces! Pretty Smart Chess Model
The most in-depth treatment of Chess strategy was presented by Levi Starrett in 'Exploring the Future'. Levi’s model recursively played hypothetical moves and counter-moves to discover the best next move. His robot can beat other robots, people and even himself! Exploring the Future
Arguably (pun intended) the presentation that sparked the most debate during the 2024 Shlaer-Mellor Days conference was titled "Zero Duration Timer Idiom and CrossFit Cindy". Cortland Starrett claimed to identify a bug in the Shlaer-Mellor Method and proposed a fix as well as a work-around (until the fix is agreed upon). And if you are a fitness nerd, this is for you! Zero Duration Timer Idiom and CrossFit Cindy
The final presentation of the 2024 Shlaer-Mellor Days conference included the results of the Chess Modeling Challenge tournament. Using BridgePoint, Levi Starrett built an executable model to run the challenge. This model played each of the bots against one another in an Arena-Style tournament. 2024 Chess Challenge Tournament Results
In-Person Gatherings
A dinner gathering is planned in the UK in Cheltenham at 19:15 on the evening of 28 October 2024. The venue is The Ivy Montpellier Brasserie. Dinner is included in the conference registration (including a significant other). Happy Hour will precede dinner at 17:30 at Sandford Park Alehouse. Come enjoy a casual brew!
