We use a fast Monte Carlo algorithm, by Newman--Ziff, for obtaining the dependence of the largest cluster size on occupation probability. The method is combined with a method, by Bastas et al., of estimating thresholds from low statistics data. The estimated values of percolation thresholds are $\\hat p_c(\\text{2NN})=0.232020(36)$, $\\hat p_c(\\text{3NN})=0.140250(36)$, $\\hat p_c(\\text{2NN+NN})=0.215459(36)$, $\\hat p_c(\\text{3NN+NN})=0.131660(36)$, $\\hat p_c(\\text{3NN+2NN})=0.117460(36)$, $\\hat p_c(\\text{3NN+2NN+NN})= 0.115740(36)$. The method is tested on the standard case of site percolation on triangular lattice, where $p_c(\\text{NN})=\\frac{1}{2}$ is recovered with five digits accuracy $\\hat p_c(\\text{NN})=0.499971(36)$ by averaging over thousand lattice realizations only.", "revisions": [ { "version": "v1", "updated": "2020-06-28T14:35:52.000Z" } ], "analyses": { "keywords": [ "triangular lattice", "site percolation thresholds", "complex neighborhoods", "fast monte carlo algorithm", "random site percolation" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable" } } }
