[sage-devel] Re: Fwd: [sage-newbie] Re: Sage for MacOS 10.5 (PPC)

Hi, First off, indeed, I do run a OSX 10.5 PPC system, and Sage does build correctly from source just fine. I've had weird build issues over time with fink installed ... I got rid of fink when I upgraded to 10.5, so I don't know if any remain. Just post to sage-support if you run into anything we

[sage-devel] Re: Fwd: [sage-newbie] Integer points on Elliptic Curves

ok, sorry about the factor of 100. Ask me if you want to know how the code works (but it is not easy). I just spent a large number of hours tracking down an error revealed by valgrind (accessing unintialized memory) which turned out to be a question of replacing < by <= in one loop. John On 21

John, I know about the GPL, but I always like to ask first! :-) I had downloaded the binary-only version, and found the .spkg file, but it's been replaced with a short text which says that it's just there as a place-holder. I've downloaded the full source now, thank goodness I'm on broadband. Yo

John, I'm interested in doing some work in this. I've just had a test run of point-search and would like to look at the source if that's OK. The version of Sage I installed doesn't include the source so I thought I'd look on the Sage website, but can't locate it there either. Am I looking in the w

[sage-devel] Re: Fwd: [sage-newbie] Integer points on Elliptic Curves

Bill, This question can be answered at (at least) two levels with very different levels of sophistication. For point searching on elliptic (and more general curves) there are lots of algorithms and implementatons. There's a stand-alone C program by M. Stoll and other called ratpoints, and my mw
