Hi, I think both the links are pointing to the same patch, which I've been working on recently--thanks for taking a look! To get the patch from trac to work, I think you need to use mercurial; there are some instructions in the sage developer guide, but in case you don't feel like going through all that I've put the two files online at
http://www.math.uga.edu/~njohnson/sage-code/multi_power_series_ring.py and http://www.math.uga.edu/~njohnson/sage-code/multi_power_series_ring_element.py It should work to just read them into a sage session, but let me know if you have trouble. The times for your code look great! If I understand correctly, the left column is from the trac patch, the middle is your code in python, and the right is your code modified to run in sage. I suspect that if you run all the tests on the same machine, the timings for your code will look even better, but maybe you could let us know if that's not the case. Could your code extend to work over other base rings? For those interested, the email link from Mario's first post contains timing comparisons between the trac patch and magma, with the general conclusion that the trac patch performs better than Magma in several cases, especially when the total degree is larger than a few hundred. -Niles -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
