I've spent a while recently with a Tate like method of generatingvalues as given by ellheight. My current gmp implementation takesabout 5 days to produce a 1000000 digit result, so it's not that quick.

As such I'm interested in writing some code using the gmp library toimplement Mestre's AGM method.

Does anyone know if the algorithm is published online or,alternatively, point me in the direction of some good information on this.



Best Regards,

Kevin.
