#4495: [with algorithm, needs implementation] weight distribution for binary
codes
---------------------+------------------------------------------------------
Reporter: rlm | Owner: tbd
Type: defect | Status: new
Priority: major | Milestone:
Component: algebra | Keywords:
---------------------+------------------------------------------------------
Using Robert Bradshaw's bitsets, which include hamming weight functions,
it should be trivial to implement a weight distribution algorithm for
binary codes in pure Cython.
Essential ingredients:
1. A list of bitsets representing the basis.
2. A zeroed array to store the weight distribution.
3. A gray code traversal of the span of the list.
4. Hamming weight functions.
This should be nearly trivial to implement, and would remove the
dependence (unmerged) ticket #4320 has on Guava, which will make the
Windows port even harder...
