13:35 Design #950: factor and SmoothFactor for integers --> FactorINT, FactorINT_TrialDiv, FactorINT_PollardRho
Here is an effect of the idea of testing the remaining factor for primality.... John Abbott

19:18 Feature #1249: principal ideal has a Gbasis
Done and partly tested. Anna Maria Bigatti
18:53 Feature #1249: principal ideal has a Gbasis
Here are some more minor points (after speaking to Anna on the phone):
* Anna was concerned about potential cost if ...

19:16 Design #1255: Ideals with trivial GBasis

19:14 Design #1255 (New): Ideals with trivial GBasis
If an ideal has a single (non-zero) generator then that generator is automatically a Gbasis.
CoCoALib does not curre...

16:03 Bug #1250: SEGV: CoCoALib with Normaliz in multithreading
The distribution had a precompiled @PREPROCESSOR_DEFNS.H@ and @autoconf.mk@ disabling @CoCoA_THREADSAFE_HACK@.
A par...

17:17 Feature #1249 (In Progress): principal ideal has a Gbasis
Also if the gens happen to have coprime LTs wrt to current ordering then they are a GBasis. Might be useful to have ... John Abbott
16:34 Bug #1248: MinPolyQuot: guaranteed and ideal without GBasis
Fixed.
Now, *guaranteed* computes GBasis if missing, so result is guaranteed.
Testing.

15:10 Feature #1254 (New): New function: MinPoly for pseudo-zero-dimensional ideals
For min polys it might be possible to work with a sub-ideal in a subring. For example,... Anna Maria Bigatti

18:39 Design #1225 (In Progress): Move to C++14 (skipping C++11)
So far I have done the following:
* revised and renamed script @cxx03.sh@ into @cxx14.sh@
* revised @configure@ scr...

16:13 Bug #1248 (In Progress): MinPolyQuot: guaranteed and ideal without GBasis
Two more comments:
* *(1)* my preference is that computations in CoCoALib be guaranteed correct unless the caller ex...

16:14 Feature #1251 (Closed): New function: radical for monomial ideal
As for zero-dimensional ideals, implement it so we can pass it to CoCoA-5. Anna Maria Bigatti
