For the GA Advantage2 prototype solver, the kink density is calculated for various coupling strengths (Jij = −1.8/κ) with time rescaled by λ(κ) assuming the published schedule and (15). Agreement is reasonable for small values of ta/λ (larger energy, shorter time), but deviate on longer time scales. Quadratic extrapolation to λ(κ) = 0 (examples shown inset) improves the agreement with simulation on longer time scales.
