Query: Study of +/-J Ising Spin Glasses via Multicanonical Ensemble   We performed numerical simulations of 2D and 3D Edwards-Anderson spin glass
models by using the recently developed multicanonical ensemble. Our ergodicity
times increase with the lattice size approximately as $V^3$. The energy,
entropy and other physical quantities are easily calculable at all temperatures
from a single simulation. Their finite size scalings and the zero temperature
limits are also explored.
