Splitting an exam across rooms multiplies its period penalty.

Member previewVariant 2 · 3 implementations · 8 checks per implementation

Case contract

Assignment rows [exam, room, period] (a split exam has one row per room; rows may repeat). Each exam pays its period penalty once per distinct period it occupies and each room penalty once per distinct (exam, room). Return [period penalty, room penalty, total].

Why this case matters

Period and room preferences are soft costs that must not be multiplied by exam splitting.
