Domain: Binary word statistics

Details

• Defined over BinaryWord as an expression in _x, evaluated by compute-engine — the definition IS the implementation.
• Takes a BinaryWord and nothing else — it reads values against their positions, or walks the orbits, so it needs the bijection. Applying it to a bare list is a type error, not a wrong answer.

Definition

Epsil, as the implementation runs it.

on BinaryWord, over _x

Fold(Function([(a[1] + 1) * b, Max(a[2], (a[1] + 1) * b)], a, b), [0, 0], _x)[2]
