The semiclassical approximation of the coherent-state propagator requires the computation of complex trajectories satisfying special boundary conditions. In this paper we present a method for the determination of such trajectories for one-dimensional polynomial potentials. We also compute the semiclassical propagator for the case {ital V}({ital q})={lambda}{ital q}{sup 2}/2+{beta}{ital q}{sup 4} and compare the results with an {open_quotes}exact{close_quotes} calculation. {copyright} 1996 Academic Press, Inc.
