Most dynamical systems exhibit a type of universal behavior in which high peaks of some field emerge from a low amplitude noisy background. In nonintegrable systems, stationary states characterized by robust coherent structures immersed in a sea of radiated wavelike fluctuations occur. This work demonstrates that such states are the most likely solutions for systems with additional integrals corresponding to surviving symmetries.
