people.eecs.berkeley.edufield methods are based on nonconvex optimization problems, which typically have multiple solutions. In contrast, Section 7 discusses vari-ational methods based on convex relaxations of the exact variational principle, many of which are also guaranteed to yield upper bounds on the log likelihood. Section 8 is devoted to the problem of mode compu-

We can thus exploit the fact that ψ0 is the ground state of a harmonic oscillator which allows us to compute the kinetic energy very easily by the virial theorem for a harmonic oscillator wave function: T = E o/2=¯hω/4.But what ω corresponds to our trial wave function a parameter? Fortunately this is easy since a = mω/¯h ...
