# The lab

> The wiki's open notebook: structural findings and named search experiments, each credited to the researcher who ran it and reproducible from source. One corner of the community's wider research.

This is the open notebook: original findings and experiments on Eternity II,
written up in full and credited page by page to the researcher who did the
work. It is not one person's blog. The
[experiments](/research/lab/experiments) are organised one section per
researcher, and each person's work also gathers on their own [contributor
page](/research/people). Today [Raphaël's](/research/people/raphael-anjou)
section is the full one, because he is the one writing things down, but the
structure is built for many hands and there is a section waiting for yours.
The community's methods, records and history live across the rest of the
research section.

## Where to start

- **[The experiments](/research/lab/experiments)** is the full gallery: every
  named search and structural finding, filterable by outcome and researcher.
  Start here to browse.
- **[Which wall stops which method](/research/why/walls-and-methods)** reads the
  gallery as one picture: each experiment against the wall it attacks and the
  score where it stopped.
- **[How the lab publishes](/research/lab/experiments/methodology)** is the
  shared editorial standard every page here meets, so you know what each label
  on a result means.
- **[Contribute](/research/contribute)** is how to add your own finding, credited
  to you, beside the rest.

The algorithms here are experiments, not breakthroughs. Some are original
ideas; others faithfully reimplement a known community technique to measure
exactly what it buys. Each write-up says which it is, what it attacked, where
it stopped, and what it left open, so anyone can pick up where it ended.

## Everything is reproducible

No result on this site is an unbacked claim. Deterministic computations ship
a runnable script and the exact output it produces. Searches that depend on
randomness or take hours ship the same script plus the board they found,
which you can load into the viewer and check edge by edge. The label on each
result tells you which kind it is.

## How the lab publishes

Every page here meets one shared editorial standard: what kind of contribution
it is, whether it publishes and at what tier, and how firmly its claim is backed.
[How the lab publishes](/research/lab/experiments/methodology) sets out that standard, so the
same rules apply no matter who writes the page.

## Add your own

The notebook is open. If you have a finding or a search worth writing down,
there is [a place for it here](/research/contribute), credited to you, sitting
beside the rest.

## Pages in this section

- [Experiments](https://eternity2.dev/research/lab/experiments) — The lab's named search experiments, one section per researcher. Each is a real run against Eternity II with its idea, its best board, and the questions it left open. Raphaël Anjou's notebook is here in full; the notebook is open to anyone else's.
