Query: A comparison of extremal optimization with flat-histogram dynamics for
  finding spin-glass ground states   We compare the performance of extremal optimization (EO), flat-histogram and
equal-hit algorithms for finding spin-glass ground states. The
first-passage-times to a ground state are computed. At optimal parameter of
tau=1.15, EO outperforms other methods for small system sizes, but equal-hit
algorithm is competitive to EO, particularly for large systems. Flat-histogram
and equal-hit algorithms offer additional advantage that they can be used for
equilibrium thermodynamic calculations. We also propose a method to turn EO
into a useful algorithm for equilibrium calculations.
  Keywords: extremal optimization. flat-histogram algorithm, equal-hit
algorithm, spin-glass model, ground state.
