Spin glasses like the three-dimensional Edwards-Anderson model show a proverbial `glassy' behavior with very slow equilibration as the result of their rough energy landscape. I.e., an energy-function that contains a multitude of local minima or metastable states separated by energy barriers. We use a newly developed dynamical greedy algorithm [1] in combination with flat-histogram methods in order to sample the distribution of these minima and compare with theoretical predictions [2].
