This page is a companion to the preprint [**The Annealed Critical Window for Growing-Radius Domination in Random Regular Graphs**](/papers/growing-radius-domination-paper.pdf) — [the full theorem-and-proof form is here](/essays/near-critical-growing-radius-domination.html). A complete, runnable version — [`growing-radius-domination-demo.py`](/papers/growing-radius-domination-demo.py) — ships alongside this page, together with [the CSV of diagnostic output](/papers/growing-radius-domination-demo-output.csv) it produces.

Naming a version control system after yourself is a mild hubris. Linus has been candid that this is exactly what he did with git — *"I'm an egotistical bastard, and I name all my projects after myself. First 'Linux', now 'git'."* LeVCS — Levi's [VCS]{.smallcaps} — admits the same joke up front and gets on with it. The work itself is the substrate: an object model, a federation [API]{.smallcaps}, a merge engine, and a small instance server, written in Rust, sized to fit on a [VPS]{.smallcaps} and audit-able by one person in a weekend.

Running a lab that develops frontier LLMs is somewhat like playing a game that, by all measurable metrics external, you are bound to lose. The amount of compute required to train a frontier LLM is unbelievably expensive. The expense of inference is even more astronomical. OpenAI claims at the time of this writing to have somewhere between 900 Million and 1 Billion active users, all of whom require some amount of inference cost, and some small subset of whom consume an enormous amount of compute - to use their words, this is ["commercial scale."](https://openai.com/index/accelerating-the-next-phase-ai/). This isn't to mention the immense amount of competition - there are many major players in the United States alone contributing models that push the boundaries. OpenAI may have been the first, but Anthropic, Google, Meta, xAI, and, yes, even Amazon and Bytedance are following right along.

There are at least two distinct ways to reduce the search space over which AGI^[The definition of "Artificial General Intelligence", or whether such a definition exists, is contentious. My use of the term is not intended to endorse any proposed timeline for AGI, nor to suggest that it is inevitable. It is rather to provide calibration through a hypothetical goal that clearly justifies pursuit.] will have to operate. The first involves a harmonious interaction of agent and human, not transactional in origin, not fully autonomous nor fully human-driven, but rather collaborative in nature - the agent augments the capacity of the human, just as any other good tool for thought does, by working within the scope of something well specified and ideated upon. This is not to say that the agent cannot have a place in such planning, but rather that the human is ultimately the driver of the actions and tasks, defining the scope of what is to be done in as much detail as possible without being the one to actually do it.

For as long as I can remember, I have believed that the deepest understanding comes from the insatiable urge to create something new in response to what you have encountered. I see no boundary on the forms such a response may take. Encountering a system invokes the urge to master and reshape it; hearing a masterpiece invokes the urge to write a symphony; finishing a novel becomes an unanswered question about that strange, irreplaceable power of fiction. This restless inquiry — consuming and creating in the same breath — is at the core of who I am.

How does one resolve the age-old dilemma of earnest self description? Is any such act of description overly humiliating and reductive in nature? Hubristic and egotistical, on the contrary? I have pondered over this subject for years, my greatest conclusion being that my actions and character should be the pinnacle of how I am described, for these form the pinnacle of what constitutes me.
