[sage-devel] Re: Missing igraph package on the mirrors?
Helloo! Sorry, David already told me about this issue, but I forgot to tell you. The problem is that, probably, the packages should be uploaded on the servers. You can find the correct versions here: igraph: https://drive.google.com/file/d/0B5D_YOccuV6xNFFUYnZFYzg0bkk/view?usp=sharing python_igraph: https://drive.google.com/file/d/0B5D_YOccuV6xcURsT1BpLUpqZ0E/view?usp=sharing Hope it will be fixed soon!

Re: [sage-devel] Re: Including external Python libraries
Hello!
I think I have solved my problem: for future reference, the solution was
written in the documentation
(http://doc.sagemath.org/html/en/developer/packaging.html).
I have opened ticket 18929 (http://trac.sagemath.org/ticket/18929) to
include igraph library: hopefully, soon it will be available in Sage!
Thank you very much!
Michele

[sage-devel] Including external Python libraries
Hello! I am trying to improve Sage graph module: to this purpose, it would be excellent to add the possibility to interface with igraph, one of the most famous graph libraries [1]. The Python interface offered by igraph [2] uses a complicated installation script [3]. However, the whole library (including the C/C++ core) can be easily installed on my Linux laptop via sudo pip install python-igraph. Do you have any idea on how to deploy igraph library with Sage? Can you suggest me another library already included in Sage, that I can use as an example? Thank you very much!

[sage-devel] Heuristics to approximate matrix bandwidth
Hi all! My name is Michele Borassi, and I recently entered this great community for a Google Summer of Code project. Among other works, I am including in Sage an algorithm for computing the Cuthill-McKee and the King orderings [1,2], which are heuristics used to approximate the bandwidth of a graph [3] (ticket 18876, [4]). Since the bandwidth of a graph is the bandwidth of its adjacency matrix, maybe these algorithms might be useful also in the matrix context. However, before including them, since I work with graphs and I know very little about matrix algorithms, I have some doubts: - Are these algorithm really interesting for matrix analysis? - In case, where and how should I include these algorithms? - If it is more complicated than this), could you provide more information? For instance, if you need related routines, like permuting rows and columns according to these orderings, or maybe you would like to integrate this work with other algorithms. In case, I might open a new ticket that takes care of all these things. For any other comment, doubt, or suggestion, please feel free to contact me! Thank you very much for your help!
