Expand description

A machine-checked certificate that a refutation’s trajectory carries a valid Lyapunov function, with the four dynamical-systems axioms verified explicitly and the resulting complexity bound.

Fields§

§initial: u64

V at the start of the trajectory.

§minimum: u64

V at the goal (its minimum, reached at ⊥).

§levels: u64

Number of distinct potential values — the length of the strict descent.

§max_dissipation: u64

The most work (steps) dissipated at any single potential level.

§size_bound: u64

The size bound the descent certifies: levels · max_dissipation.

§total_steps: u64

The actual number of trajectory steps (≤ size_bound).

§monotone: bool

Axiom 2: V never increases along the trajectory.

§strict_descent: bool

Axiom 3: V strictly decreases across its level set (no level recurs — guaranteed progress).

§reaches_goal: bool

Axiom 4: the trajectory reaches the goal (the refutation closes at ⊥).
