Checklist ONIA 2026 County Stage, Grades 11–12 · Task 2
Juditis Mission
Romanian title: Misiunea Juditis
Compute two statistics of a comic-book hero dataset, regress the combat power statistic and classify the Super Strength ability.
The task
After a cosmic event merged several comic-book universes, an agency collected data on the heroes: descriptive attributes (publisher, gender, race, eye and hair colour, height, weight, alignment), binary abilities and numeric power statistics.
Task 1 asks for the number of distinct publishers and task 2 for the publisher with the most heroes of 'good' alignment (ties broken alphabetically). Task 3 asks for powerstats__combat and task 4 for the binary Super Strength ability of each hero in test.csv.
Abridged and translated by SOTA from the official Romanian materials. The official statement has the exact rules, and it wins wherever this summary differs.
At a glance
- You get
train.csv(505 rows, 103 columns) andtest.csv(100 rows, without powerstats__combat and Super Strength). Archive of 82,121 bytes.- You submit
- CSV with id, subtaskID (task1–task4) and answer; tasks 1–2 use id GLOBAL; task 4 answers are 0.0 or 1.0.
- Scoring
- Tasks 1–2 (10 points each): exact match. Task 3 (40): MAE; 40 points if MAE ≤ 12.0, 0 if ≥ 30.0, otherwise 40 × (30 − MAE)/(30 − 12). Task 4 (40): accuracy; 40 points if ≥ 0.90, 0 if ≤ 0.55, otherwise 40 × (acc − 0.55)/(0.90 − 0.55).
