We find that the critical exponent associated to the order parameter (percolation probability) is beta=(1-1/\\sqrt{5})/2=0.276393202..., in remarkable agreement with the best current numerical estimate beta=0.276486(8).", "revisions": [ { "version": "v2", "updated": "2002-05-28T23:42:08.000Z" } ], "analyses": { "keywords": [ "directed percolation", "precise approximation", "dimensional directed bond percolation", "best current numerical estimate", "approximation specific" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
