i wonder is this applicable to systems which is far-from equilibrium? Or even if it is far-from-equilibrium, we can still somehow use "variational principle" to attack such problem? thanks
Yes, it is possible because this formalism consider an ensemble of events at each time scale separately. Therefore, time plays a role similar to the inverse temperature of a heat bath. Not immediate to grasp, I agree.
