DESCRIPTION:Speakers: Dušan Vudragović (IPB)\nNumerical convergence of q
 uantum mechanical transition amplitudes to their continuum values is signi
 fically increased by the Path Integral Monte Carlo effective action approa
 ch. Using this approach\, long-time quantities are obtained by integrating
  over the short-time ones\, which assume expansion of the effective potent
 ial to power series in the time step to a given order. This optimized Path
  Integral Monte Carlo algorithm is implemented in the SPEEDUP code. In thi
 s paper we describe further improvements of the\nalgorithm through the use
  of the scaled bisection algorithm and quasi-Monte Carlo method for effici
 ent generation of relevant trajectories for several simple quantum models.
