We study the bimodal Edwards-Anderson spin glass comparing established methods, namely the multicanonical method, the $1/k$ ensemble, and parallel tempering, to an approach where the ensemble is modified by simulating power-law-shaped histograms in energy instead of flat histograms as in the standard multicanonical case. We show that by this modification a significant speed-up in terms of mean round-trip times can be achieved for all lattice sizes taken into consideration.

旋转眼镜的非平面直方图技术

我们比较了已建立的方法，即多规范方法， $\mathrm{1个}/ķ$集成和并行回火，这种方法是通过模拟能量中的幂律形直方图而不是像标准多规范情况中的平坦直方图来修改整体的方法。我们表明，通过这种修改，可以将所有晶格尺寸的平均往返时间显着提高。
