There are a huge number of things missing. 1. a fast minimum_distance for an arbitrary non-binary code (minimum distance of linear binary codes can be computed very quickly thanks to code by Robert Miller) 2. a function to compute a basis for the Riemann-Roch space of a reasonably general curve at a reasonably general divisor. This is needed to implement AG codes.) 3. implementation of the "weight function" machinery (this is an alternate way to compute certain AG-type codes, avoiding the Riemann-Roch space machinery; see the survey papers by Hoeholdt on AG codes...) 4. decoding algorithms 5. covering codes and covering radius algorithms (more generally, porting over Guava functions to Sage) 6. more generally, porting over what Magma has that Sage doesn't. >> >> >> On Thu, Oct 15, 2009 at 9:00 PM, William Stein <wst...@gmail.com> wrote: >>> >>> Hi, >>> >>> I'm applying to NSF for some Sage Days workshops (off in the future: >>> think 2-4 years from right now).
