Concentrations of A bonds are varied in the interval 0.00, 0.11, where a spin-glass phase has been characterized by means of the Binder cumulant technique. Many random samples are prepared for each different sample size and for each concentration to allow a basic statistic analysis. For each sample a single spin-flip Monte Carlo process is performed at different temperatures, recording the evolution of the Edwards-Anderson parameter q. Each one of these runs is stored in a separate file for subsequent studies. Thus, for instance, the time autocorrelation function is found for each of these numeric experiments. Functions corresponding to different sizes cross as a funtion of temperature in a way similar to Binder cumulants also leading to phase characterizations. The line separating a ferromagnetic phase from a spin-glass phase obtained by the new method is reported. On the other hand, size of the compressed stored filed maximize at the critical temperature, for reasons not yet understood.
