20:08 Feature #667: factor: multivariate + finite characteristic: Factorizing in @F_q[x]@ is largely the same as factorizing in @F_p[x]@; the algorithm is essentially the same (but co... John Abbott

13:31 Feature #667: factor: multivariate + finite characteristic: The squarefree decomposition is the normal first step, but there are other problematic steps (_e.g._ mapping down to ... John Abbott

11:23 Feature #667 (New): factor: multivariate + finite characteristic: (if I remember well)
The problem about factorizing a multivariate polynomial in finite characteristic was just the s... Anna Maria Bigatti

13:36 Bug #666 (In Progress): RatReconstructByLattice fails in some simple cases: I now think that the problem may really be imprecise documentation.

17:56 Bug #666: RatReconstructByLattice fails in some simple cases: It seems that *both* @RatReconstructByContFrac@ and @RatReconstructByLattice@ *fail* on (1,N) for N < 1145. Then the... John Abbott
15:04 Bug #666: RatReconstructByLattice fails in some simple cases: I ran the following to compare when ContFrac and Lattice methods are better... John Abbott
15:01 Bug #666 (Closed): RatReconstructByLattice fails in some simple cases: @RatReconstructByLattice(1,1145)@ returns failure -- why?? John Abbott

20:59 Feature #24: object files collected in one directory: Right now I do not recall why we think it is a good idea to have all object files in a single directory.
Pro:
* e... John Abbott
20:37 Feature #24: object files collected in one directory: Here is an example I found on the internet; it uses GNU make's VPATH facility:... John Abbott
20:46 Feature #664: Impl small non-prime finite fields (using logs): When char=2 we can readily use (binary) integers to represent field elements.
The idea is to find a generator @theta... John Abbott
20:41 Feature #665: Integrate Janet/Pommaret basis code: Mario will try to put all his source code in his own namespace (perhaps called @involutive@), and will put all his fi... John Abbott

10:33 Feature #651: Optimized algorithms for implicitization (slicing algorithm, elim, subalgebra..): I changed all ring names into Kt and Kx in TmpImplicit.C
