# list of algorithms not implemented in Sage for contributors

Hello all! I would like to know if there is some list of algorithms that are not implemented in Sage and that are important (for ex. because of its speed). I think that it would be great for contributors. I believe the greatest things are mostly free and that Sage is very good example of this. Lot of algorithms in Sage are the fastest (when I compare it with 'ma' softwares) and that is really amazing that something free and open source for everyone can do it! For this reason I would like to contribute to this project and think that the list of important algorithms that arent still implemented in Sage would be great 'to do list' for contributors. Thanks, Martin
