We study the solution of the focusing nonlinear Schrödinger equation in the semiclassical limit. Numerical solutions are
presented for four different kinds of initial data, of which three are analytic and one is nonanalytic. We verify numerically the
weak convergence of the oscillatory solution by examining the strong convergence of the spatial average of the solution.

1. Introduction
Many dynamics in nature undergo dispersive pro-
cesses, while the dissipative or diffusive mechanisms
are negligible [23,30]. Examples include the vortex
sheet problem of incompressible fluids [16], plasmas
