15:17 CoCoALib Feature #1198: Non-standard DegRevLex (NonStdDegRevLex, WDegRevLex)

In particular we should have a dedicated @OrdvArith@ implementation for it.
This should make @exponents@ faster, a... Anna Maria Bigatti

00:39 CoCoALib Design #1177: File names: use "SparsePolyOps" prefix for pertinent files

I think the content of @SparsePolyOps.C@ (the original ;-) should be now moved into @SparsePolyOps-RingElem.C@ becaus... Anna Maria Bigatti

08:59 CoCoA-5 Bug #1190: HilbertBasisKer: SEGV (again)

The problem is that this is old C code (@toric@), thus it impossible to make it interruptible (we can interrupt it, o... Anna Maria Bigatti

09:52 CoCoA-5 Design #1194 (Rejected): Rename HilbertBasisKer into LinKerHilbertBasis?

The functions @HilbertBasisKer@ and @LinKerBasis@ have the same kind of input and output.
Maybe this would be cleare... Anna Maria Bigatti
