The data are sorted by model ---------- Edwards-Anderson Ising spin-glass model The Hamiltonian of the Edwards-Anderson Ising spin glass model is given by H = -Σ<i,j> Ji,j σi σj , where the sum extends over nearest-neighbor bonds of a hyper-cubic lattice with bond-weigths Ji,j that are drawn at random from a distribution (Gaussian, bimodal, etc), typically symmetrical with zero mean and unit variance. It is believed tha… text/html 2008-07-03T11:58:51+02:00 hgk http://www.stat-phys.org/doku.php?id=start&rev=1215079131&do=diff Goals of this site: * Provide test instances for optimization algorithms for physical problems. * Provide data sets (e.g., finite-temperature Monte Carlo) to test algorithms. * Provide a data repository for published papers using numerical results. text/html 2008-06-29T18:35:30+02:00 hgk http://www.stat-phys.org/doku.php?id=finite-temperature_data&rev=1214757330&do=diff In this page finite-temperature Monte Carlo for different models are presented.
