The classical theory of shear melting induced instability can be evaluated by a combination of variational principles and numerical minimization techniques. The method can be generalized to any system induced towards instability by an outside agency.

## The quanta1 time evolution of a one-dimensional Gaussian wave packet according to the time-dependent variational principle (TDVP) is shown to be formally equivalent to the classical motion of a particle in a two-dimensional potential. The formal and practical advantages of the TDVP approach are
