F_5 algorithm

Plan

  1. Because the original paper includes many errors and lacks strictness, read Steger's thesis instead first.
  2. Then read F5C paper to improve it.
  3. Read the paper on termination and apply its argument to F5C.

Original paper. This includes some errors and have an issue on the proof of termination. Faugère's F5 Algorithm Revisited
More accurate and comprehensive description on F_5 algorithm. This paper notes on termination, but doesn't guarantee termination for general inputs. F5C: a variant of Faugère’s F5 algorithm with reduced Gröbner bases
Improved version of F5 algorithm, which computes reduced bases in internal computation. This algorithm is not proven to be terminate for general input cases. Faugère's F5 algorithm: variants and termination issues
A short slide on F5 algorithm. This discusses on improvements and how to make F5 algorithm to terminate for general cases. Modifying Faugère's F5 Algorithm to Ensure Termination
This paper discusses several ways to make F5 algorithm terminate for not only regular sequences but also general cases.

F_4 algorithm

A naive implementation has been done before GSoC starts. As we have to implement more efficient matrix triangulation, I'll read the following papers:

A new efficient algorithm for computing Groebner basis F4
Original paper. Current implementation is based on this paper. An Implementation of Faugèere's F4 Algorithm for Computing Gröbner Bases
Paper on the detail of the implementation of F4. Maybe informative for matrix triangulation methods.

structured Gaussian Elimination

Cabarcas's paper suggests that it'd be better to use the simplified version of structured Gaussian Elimination but not describe the detail of its algorithm (for example, how to determine columns "light" or "heavy").

Here is some references which might be useful:
