Lattices in Sage: My Eclipse/PyDev/git workflow for Sage

http://gsoc-sage-lattices.blogspot.com/2012/06/my-eclipsepydevgit-workflow-for-sage.html

Google Summer of Code 2012 project by Jan Pöschko. Monday, June 4, 2012. My Eclipse/PyDev/git workflow for Sage. I want to briefly describe how. I code for Sage so that others can comment on how to improve the workflow or maybe learn something from it. For Python (and actually for all programming languages, meanwhile), I've always been using Eclipse. As an IDE. With PyDev. I have added the complete Sage tree (which is located in /Applications/sage/ on my Mac) as an Eclipse project. As recommended. Which ...

Lattices in Sage: August 2012

http://gsoc-sage-lattices.blogspot.com/2012_08_01_archive.html

Google Summer of Code 2012 project by Jan Pöschko. Friday, August 24, 2012. Update on class structure, lattice constructors, plotting. Sorry that I haven't posted to this blog for a while. That doesn't mean that nothing happened in the meanwhile—on the contrary, I got quite a lot done in the last weeks of this Summer of Code. First of all, I completely redesigned the class structure for lattices in Sage. Accounting for the discussion on sage-devel. Or via the standard real inner product). Represents latt...

Lattices in Sage: May 2012

http://gsoc-sage-lattices.blogspot.com/2012_05_01_archive.html

Google Summer of Code 2012 project by Jan Pöschko. Sunday, May 27, 2012. To have everything in one place, I want to add the time schedule from the original project proposal to this blog as well:. Get detailed insights in relevant existing Sage classes and functions. Basic class structure and factory function. Approx. one week of work for exams etc. Extensive testing of the core algorithms. Successive minima, special case for 2-dimensional lattices. 1 week for optional further algorithms. Link href="http:...

Lattices in Sage: Voronoi cells

http://gsoc-sage-lattices.blogspot.com/2012/07/voronoi-cells.html

Google Summer of Code 2012 project by Jan Pöschko. Sunday, July 8, 2012. Recently, I have implemented the diamond-cutting algorithm to calculate the Voronoi cell of a lattice as described in the paper Computing the Voronoi Cell of a Lattice: The Diamond-Cutting Algorithm. By Emanuele Viterbo and Ezio Biglieri. The algorithm considers vectors within a certain distance from the origin. This radius can be specified explicitly to speed things up significantly; if not, a "conservative" safe choice is made.

Lattices in Sage: Rebasing to Sage 5.2

http://gsoc-sage-lattices.blogspot.com/2012/08/rebasing-to-sage-52.html

Google Summer of Code 2012 project by Jan Pöschko. Thursday, August 16, 2012. Rebasing to Sage 5.2. As there were some changes to Sage since version 5.0 that also affect my code, I rebased my code from Sage 5.0 to 5.2. That meant installing the latest version, cloning a new branch "lattices", and manually copying over the lattices files and re-doing respective changes to some global files. I retained the 5.0-compatible version as a separate branch. Whereas the main branch on github. Posted by Jan Pöschko.

Lattices in Sage: June 2012

http://gsoc-sage-lattices.blogspot.com/2012_06_01_archive.html

Google Summer of Code 2012 project by Jan Pöschko. Wednesday, June 20, 2012. Update on basis coercion, LLL and Fincke-Pohst. As written in a previous post. I tried to prevent FreeModule from coercing its basis vectors to the fraction field of its ambient space, mainly motivated by the fact that I wanted floating-point numbers to remain "inexact" and not being converted to rational numbers. However, the resulting discussion on sage-devel. Furthermore, I added a shortest vectors method to Lattice ZZ in RR ...
