Governing equation

x min f (x), x_{n + 1} = x_{n} - η \nabla f (x_{n}), η = 0.01, x_{0} = 2.5, x^{⋆} \approx - 1.301

Reading this result: Descent from x₀ = 2.5 settled at x ≈ -1.30. With input σ = 0.4, the output spreads to about 2.21 — uncertainty stays tight near a flat minimum but gets amplified where the curve is steep.
