Phys. Rev. Lett. 69, 2292–2295 (1992)New approach to spin-glass simulationsReceived 13 April 1992; published in the issue dated 12 October 1992 We present a recursive procedure to calculate the parameters of the recently introduced multicanonical ensemble and explore the appraoch for spin glasses. Temperature depenedence of the energy, the entropy, and other physical quantities are easily calculable and we report results for the zero-temperature limit. Our data provide evidence that the large L increase of the ergodicity time is greatly improved. The multicanonical ensemble seems to open new horizons for simulations of spin glasses and other systems which have to cope with conflicting constraints. © 1992 The American Physical Society URL:
