IOAI 2026 — IOAI Field
Official contest data for IOAI Field, task 6 (Day 2) of the IOAI 2026 Individual Contest, held in Astana, Kazakhstan.
The IOAI logo is modelled as a spatial function F(x, y, W) over the unit plane. Contestants train a small network from scratch (no pretrained weights, ≤ 20,260 parameters) to reproduce the field; the grader overlays hidden leaderboard configurations onto the training config and retrains the submitted notebook.
The task statement, translations, baseline and grader live in the IOAI-2026 GitHub repository. This repository holds data only and is not published.
