Generator

One subspace, solved and regularised, at 1.0% noise

One function in the hybrid library, called 6 times across 1 essay. Below: what it draws at its defaults, what it draws at every value an essay asks for, the 5 claims it put to the test while drawing them, and where it stands against the rule this site is named for.

At its defaults it draws one subspace, solved and regularised, at 1.0% noise. Two error curves against the number of bidiagonalisation steps, on a logarithmic vertical axis. The unregularised iterate reaches 0.1426 at step 20 and then climbs to 161 — a factor of 1127. The iterate with a penalty on the projected problem reaches 0.1429 and stays within 0.00% of it for the rest of the run.

hybrid-curves is one function in lib/figures/hybrid.js — hybrid regularisation — a penalty inside the subspace, and the rule that transfers to it. Everything below came out of it during this build, at arguments taken from the essays rather than invented for this page. A figure here is the figure a reader meets in an essay, and if the generator changes, this page changes with it.

At its defaults

Drawn even though every essay passes arguments — which on this site is every essay, at 100% of placements since the standard pass. A default nothing exercises is a trap for the next essay to call this with none, and this is the page where a default that has drifted from the figures around it becomes visible.

What it checked while drawing

Every figure above checked its own claims on the way to being drawn, and a claim that failed would have stopped the picture rather than shipped a wrong one. Those checks used to leave no trace at all: a passing one returned true and the only evidence the figure had checked anything was that nothing crashed. The list below is what they actually said, collected by running this generator with an observer installed — not a description of what it is believed to check.

5 distinct claims across 6 sets of arguments, grouped below by shape — because most of them are one sentence with a different number in it, and how many separate times that sentence was put to the test is the informative part.

a noise level small enough to be noise

a size the reference solve is affordable at

and the regularised one does not

enough steps for the unregularised run to turn

the unregularised run leaves its own best behind

Against the rule

The rule does not apply to it. It factorises nothing, so there is no residual it could be withholding. That is worth stating rather than leaving blank: a site that reported the rule as satisfied by every generator would be counting mostly generators the rule never reached.

Across the library: the rule bites on 217 of 397 generators — 199 print a residual and 18 are exempt with a published reason; 180 factorise nothing. Read from lib/residual-rule.js, which is the same body the gate enforces from, and the gate's last check fails the build if this page and it disagree about any generator.

Where it is called

Changing this generator changes every figure on this list. That is what makes the list worth publishing rather than keeping in a check script.
