* Improved precision and performance when calculating analytic rank (William Stein) -- When calculating the analytic rank of an elliptic curve, the default is to use Cremona's {{{gp}}} script, where the precision is automatically doubled until it doesn't fail. The precision is started at 16 rather than the previous default precision. The computation is now about 3 times faster usually by starting off using this smaller precision. |
Sage 3.3 Release Tour
Sage 3.3 was released on FIXME. For the official, comprehensive release notes, see sage-3.3.txt. In general terms, the following points are some of the foci of this release:
- Clean up various doctest failures from 3.2.3
- Fix some build issues from 3.2.3 on the new set of supported images
- Merge small to medium sized patches ready to go in
- Switch to eMPIRe
- Switch to ecl
- Update Python to 2.5.4
- Update Pari to 2.3.4svn
Here's a summary of features in this release, categorized under various headings.
Algebra
Transitivity for permutation groups (William Stein) -- In the permutation group module permgroup.py, the query function is_transitive() returns whether or not the group is transitive on [1..G.degree()]. A few surrounding docstrings are fixed and doctest coverage for the file sage/groups/perm_gps/permgroup.py is now 100%.
Algebraic Geometry
Improved precision and performance when calculating analytic rank (William Stein) -- When calculating the analytic rank of an elliptic curve, the default is to use Cremona's gp script, where the precision is automatically doubled until it doesn't fail. The precision is started at 16 rather than the previous default precision. The computation is now about 3 times faster usually by starting off using this smaller precision.
