From e80955e77cc86ff90246f1a1dfd2f8b61ea53a45 Mon Sep 17 00:00:00 2001 From: Denis Drobyshev Date: Tue, 11 Aug 2026 00:28:39 +0300 Subject: [PATCH] Show stadion's numbers instead of describing them The site said stadion places a score between the classical method and the optimum, and then left the reader to take that on trust. The measurements exist - six tasks, the distance between the two references, each with a bootstrap interval - and they are the most convincing thing the project has. The spread is what the table is for. Inventory leaves 0.4% because the newsvendor formula is already near-optimal; the battery leaves 26.6% because a price threshold cannot decide to arrive at the evening peak with charge in hand. A benchmark whose tasks all leave generous headroom has selected for problems the standard method happens to be bad at, and this one can show that it did not. Figures copied from the repository's own README table rather than recomputed, and the caption carries the conditions so the column can be read without the repository open. --- assets/site.css | 39 +++++++++++++++++++++++++++++++++++++++ index.html | 23 +++++++++++++++++++++++ ru/index.html | 23 +++++++++++++++++++++++ 3 files changed, 85 insertions(+) diff --git a/assets/site.css b/assets/site.css index 37a54ea..42ebb66 100644 --- a/assets/site.css +++ b/assets/site.css @@ -429,6 +429,45 @@ h4 { font-size: .8125rem; } .copy-btn svg { width: 14px; height: 14px; } .copy-btn[data-copied] { color: var(--accent-2); border-color: var(--accent); } +/* A measured table inside a project block.
