The forward-backward semiclassical dynamics (FBSD) method alleviates the notorious quantum dynamical sign problem through pre-cancellation of the forward and backward classical action integrals; the resulting quasiclassical scheme has been applied successfully to condensed phase systems as quantum mechanical as superfluid helium. Recent developments in FBSD have accelerated convergence with respect to the number of imaginary time steps; applications to model anharmonic systems and Lennard-Jones fluids will be discussed.

Bailey's generalization of Hamilton's principle of stationary action has been used to solve Bohm
