22:15 CoCoALib Bug #1758 (In Progress): Graeffe "sign bug"
- Currently, trying to compute @graeffe(f)@ over a finite field produces:...

22:10 CoCoALib Bug #1758 (Closed): Graeffe "sign bug"
- I put in a (not-so) "clever trick" in @graeffe@ and @graeffe3@ so that the LC is positive if the coeff rings is @ZZ/Q...

13:52 CoCoALib Feature #1755: CheckForInterrupt: give more info?
- Create an example of using *@GetAndResetSignalReceived@*

19:31 CoCoALib Slug #1754: IsSqFree poorly implemented
- I have improved the code. It is also a bit faster (than 0.99818).
Will check in soon.

18:04 CoCoALib Slug #1757: gcd(f,f) is slow
- Here is just 1 example illustrating the point:...
-
18:03 CoCoALib Slug #1757 (New): gcd(f,f) is slow
- Consider making a special case of @gcd(f,f)@ or indeed @gcd(f,k*f)@ where @k@ is a scalar.

18:01 CoCoALib Slug #1754 (In Progress): IsSqFree poorly implemented
- Source code around @NumTheory-factor.C:690@

09:32 CoCoALib Slug #1756: deg(f) is slow if f is long
- Oddly, i believed I had recently sorted this out... evidently not.
We need a function to say whether the ordering on... -
09:29 CoCoALib Slug #1756 (In Progress): deg(f) is slow if f is long
- In a poly ring with a std deg compatible order we can compute @deg(f)@ just by looking at the first PP.
It seems we ...

17:46 CoCoALib Feature #1755 (Feedback): CheckForInterrupt: give more info?
- After discussing with Anna (by phone), we think that extending @CheckForInterrupt@ as suggested in comment 2 above is...

15:11 CoCoALib Feature #1755: CheckForInterrupt: give more info?
- While it is not really much shorter, I was thinking of trying to implement an extension of *@CheckForInterrupt@* whic...

19:54 CoCoALib Feature #1755: CheckForInterrupt: give more info?
- Here is how I managed it in my ad hoc program:...
-
19:52 CoCoALib Feature #1755 (Closed): CheckForInterrupt: give more info?
- This may be not so important...
Today I wanted to interrupt a long loop and know roughly how far the computation had... -
16:35 CoCoALib Slug #1754: IsSqFree poorly implemented
- Ahh! I misread the code. It is not as "stupid" as I thought, but it still needs improvement (for machine integers -...
-
16:25 CoCoALib Slug #1754 (Closed): IsSqFree poorly implemented
- I think *@IsSqFree@* for integers is probably poorly implemented.
Investigate, and improve. -
12:25 CoCoALib Design #1753 (Closed): Clean up EulerTotient, InvTotient jungle in NumTheory-misc
- The various functions for computing *@InvTotient@* are now rather a mess.
Clean this up, and revise documentation.

12:14 CoCoA-5 Feature #1752: Make it easy to run the tests in a public/distrib version
- One possibility is to include the @src/CoCoA-5/tests@ directory in the distribution... it is no doubt small in compar...
-
12:12 CoCoA-5 Feature #1752 (New): Make it easy to run the tests in a public/distrib version
- It is not currently so easy to verify that the distributed "pre-compiled" version of CoCoA-5 passes all the tests.
M...

18:13 CoCoA-5 Support #1751 (In Progress): Manual of functions vs ManExamples
- In the manual we have things like these:...

17:49 CoCoALib Design #1378: Create two separate radical fns (for 0-dim ideals)
- After discussing, we have decided to postpone this until a real use-case comes up.
Postponing indefinitely.
-
16:12 CoCoALib Design #1750: IdealOfPoints: allow duplicate points?
- If we decide to permit duplicate points, implementation should be conceptually very easy... just tedious.
And don't ... -
16:11 CoCoALib Design #1750 (In Progress): IdealOfPoints: allow duplicate points?
- In a recent email a user (puwu) reported a "bug" in CoCoA.
The supplied program wanted to compute *@IdealOfPoints@* ... -

14:51 CoCoALib Bug #1749 (Closed): Configuration hiccups on Mac M1
- Max Horn reported by email several configuration/compilation hiccups on Mac M1 platform.
Investigate & fix.
