The algorithm (and the definition of y) are given in the paper mentioned in the same post: Math Of Comp 1996 by Deleglise & Rivat : Computing Pi(x), the Meissel, Lehmer, Lagarias, Miller, Odlyzko method. I found an online copy: http://cr.yp.to/bib/1996/deleglise.pdf Fredrik --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
