13:10 CoCoA-5 Support #1663 (New): GCDList not documented
- The fn @GCDList@ is not documented.
-
- I have done the example files... I hope no mistakes.
What about @ex-BencharkToolkit.C@? I have not changed that (c...
11 Feb 2022
-
- How many files are affected? How many would need to have new names?
We could try contacting the txt2tags people to ... -
- I have checked in yesterday's changes... lots of files.
Anna could you do a few spot checks to make sure that the on...
10 Feb 2022
-
- I've done most/all files in @doc/txt/@ and @include/CoCoA/@ and @src/AlgebraicCore/@ and @src/tests/@.
Still to... -

-
- Did you try following comment 10?
09 Feb 2022
-
- Bruns reported by email a problem compiling on Microsoft:...
-
- The code is there, and there is a test: @test-PPMonoidSparse1.C@. However many lines are commented out in the test.
... -
- I have also had success with @normaliz-3.9.2@ (just released). I did see several compiler warnings (about normaliz c...
-
- My 13 year old MacBook now has MacOS 10.11.6. So if anyone is stuck on 10.6.8, they must have a very old computer.

08 Feb 2022
-
- I have done the mind-numbing name replacement. All compiles OK: fewer warnings with clang.
Checked in. I wonder i...
07 Feb 2022
-
- I think I might impl the suggestion in comment 4. We can easily change the name later... just a global subst.
Poor ... -
- I think there was some doubt as to what the correct name for this fn should be.
Don't recall the outcome: see issue... -
- Written doc; added xrefs.
Found a bug (from the example put into manual); fixed it.
Will check in shortly.
-
- It seems that @LinKerZZ@ is callable from CoCoA-5, but is not documented.
Rectify (after checking that code is robus... -
- CoCoA-5 can compute @eigenvectors@ (in a particular way).
Would it make sense to try to make it compute Jordan block...
06 Feb 2022
-
- Current CVS compiles, runs and all tests pass on Linux-64, Linux-32 and my old MacBook.
05 Feb 2022
-
- I have changed the impl of the fn @copy-CoCoAManual@. I have checked it in without testing!!
*Anna:* please check m... -
- I do not like the function @copy-CoCoAManual@ in the script @release-common.sh@.
Currently it copies everything, and... -
-
- Postpone?
-
- I compiled normaliz on my old MacBook without any problems (following the instructions above, in comment 10).
-
- According to the message at the bottom of each screen in redmine, the version we are using is about 5 years ago.
We ... -
- I have renamed the files as in comment 2.
Any chance of getting the doc sorted out?
-
- Since I am hoping to make a release quite quickly, I prefer to postpone this issue to the next release (so we have ti...
-
- I have made a trivial impl (& written short doc).
Must also make available from CoCoA-5 (with doc).
-
- I have just tried "mindlessly" changing names as suggested above on my MacBook.
That did indeed eliminate those tedi... -
- I compiled on my MacBook yesterday, and all went well except for numerous warning about "hidden member fn" (or simila...
04 Feb 2022
-
- Now everything compiles and all tests pass.
Will check in soon.
I think I have changed the doc too!
-
- I have just renamed @MakeTermOrd@ to *@MakeTermOrdMat@*.
Checking that everything compiles; then will check in.
-
- The first line in commenrt 10 above is still about 50s... too slow!
How long does it take to compute the det of a 50... -
-
- I compiled Normaliz without any problems: here are my notes:...
-
- This has been in feedback for 4 months without incident, so we can close.
-
- There is a file called @SparsePolyOps.txt@ which seems to be devoid of meaningful content.
There are several files w... -
- This should be updated after I have updated my Linux box (still on Ubuntu 18.04).
-
- How should this be done in a systematic way (which can be paused)?
Postponing since it is just "tidying up".
We mus... -
- This is another "long and tedious" job. It needs to be done, but better when time pressure is less.
-
-
- This should not be hard, but will probably take quite a lot of time... which is very scarce at the moment.
Postponin... -
-
- *Anna* please check everything is OK on your computer!
-
- No one has howled in the last 3 months, so closing.
Maybe on the next trip to Genoa I can check on Anna's computer. -
- Let's cross our fingers and hope that the problem has gone away by the time we jump to C++20.
Closing this issue....... -
- *This probably needs changing* after issue #1655.
How does this issue differ from #1591 ?
-
- This is still not documented -- Anna can you do this?
Should the code be put into @SparsePolyOps-vector@?
Presuma... -
- I have added a test to @exbugs.cocoa5@ -- the one given in the description.
Closing.
-
- The code works. If there is a real use-case where the low speed is a problem then we can create a new issue.
I thin... -
-
- Maybe not perfect, but surely most cases have been added.
Not time efficient to search for any missed cases. Closing. -
- Maybe the current impl is not perfect, but it is good enough for these tests.
Closing.
-
- This has been at 90% for 3 months.
Cannot be bothered to check now. Just closing.
-
- I have documented @MinGBoverZZ@ but no other function. It is clearly marked as @[PROTOTYPE]@.
The package is now ca...
03 Feb 2022
-
- I have added a quick test in @BuiltinFunctions-MathSAT.C@.
A very quick test worked as hoped. But it needs more tes... -
- Status?
Even something hasty is perhaps better than nothing?
-
- I have been postponing lots of issues which cannot be closed in the very immediate future.
I really hope we can get ... -
- If we do make a hurried release (as I recommend), should we include a "health warning" that it is a hasty release?
-
- I'm wondering whether we should release 5.3.4 as soon as practicable... otherwise I doubt I'll be able to help make a...
-
- I do not want to lose this, but there is never time... grrr!
-
- Either do it fast for 5.3.4, or postpone to next release!
If you can write some simple doc quickly, we get the benef... -
- This is one of those "tedious but necessary tasks" for which it is almost impossible to find time.
So postponing....... -
- Postponing once again.... we must eventually actually do this!
-
- The comments suggest that this issue is essentially fixed.. so I have advanced the status to feedback.
-
- No complaints in several months... must be OK.
Closing!
-
- This issue has been dormant for 2 years. I suppose whatever the problem was has gone away.
Closing!
-
- A student (Nico Mexis) here in Passau has reported succeeding getting GFan working on Microsoft.
How to find time to... -
- Can we close this issue? If not, postpone it!
-
- I suppose the current status must be acceptable. No problems have been reported for a year.
Close?
-
- Is this issue now resolved satisfactorily?
I guess so. If so, close it!
-
- Is this issue acceptably resolved? Close now?
-
- So that we do not lose what has been done....
I suggest making the existing code into an official package; we should... -
- What is the future of this package?
Florian is now rather busy with other things, so cannot in the foreseeable futur... -
- Is this resolved to a satisfactory degree? I think @BringIn@ and @RingElem(P, string)@ cover most use cases.
Can we... -
- The impl is rather messy.
I suppose the bus is not so terribly bad: it has not (apparently) caused trouble, and the ... -
- Too much stress to keep this open any longer. I'm pretty sure it is fixed now (and faster too).
Let the users do th...
02 Feb 2022
-
- I have a first version with modulus. I think it is probably faster, but still impressively slow :-/
I'll wait a bit... -
- To be ale to tackle non-trivial examples, it would be very helpful to have a way of reducing polynomials modulo any c...
-
- I have done some cleaning in the code, and have added a @SortBy@ to the list of pairs.
It seems to make the code run... -
- What is the status of this issue?
Is the latest version of the code above more-or-less ready to be included in a rel... -
- There is probably an implementation in the "Gbasis over ZZ" package: see issue #1272.
-
- Oh joy!
Have fun if you decide to document functions whose name contain an underscore: LaTeX gives its usual crypt... -
- I have updated the doc, and checked in everything.
Hope Anna can check on her machine soon.

- I have now implemented *@FactorINT@*, *@FactorINT_TrialDiv@* and *@FactorINT_PollardRho@*.
@SmoothFactor@ is now o... -

- I have modified the impl of @SubsetsN@ in @combinatoria.cpkg5@ so that it handles 2-subsets specially (avoiding recur...
29 Jan 2022
-
- There are now 2 @resultant@ functions and 2 @discriminant@ functions(in each case with or without specified indet).
... -
- The problem was in some unrefined code for computing subresultant sequences.
Now it is more robust.

- A quick way to SEGV:...
28 Jan 2022
-
- Winfried pointed that I'd made a typo (now fixed).
A new version (normaliz-3.9.2) should be appearing in the near fu... -
- All seems to be fine even with Normaliz-3.9.1.
-
- Since @resultant@ is closely related to @discriminant@ they should have compatible behaviour.
This includes presumab... -
- Anna agrees with what I'd like to do.
Should something similar be done for @resultant@ too? -
-
-
- I have just compiled successfully.
Need to update doc in ExternalLibs-GMP.txt
Anna will check in her machine soo... -
- I think the only real change needed is in the script @configuration/gmp-find-hdr.sh@
Perhaps it should print out a h... -
- JAA now thinks that what we do is wrong rather than "clever".
Unless AMB objects, we should make this change quickly.
-
- This proposal is to modify the configure script so that it does not accept an *uninstalled* GMP.
A use who does not ... -
- I have just checked, and observe that there is now Normaliz 3.9.1.
I shall try compiling.
*UPDATE* Compiled with... -
- Anna, could you please describe more explicitly what you are proposing?
I am not sure I understand from the issue de... -
- It seems that Anna accidentally reset the progress for this issue... maybe she had two browser tabs on the same issue...

Though that does read rather like an error message... -
- I suggest making @SmoothFactor@ obsolescent, and just forward the call to @FactorINT_TrialDiv@.
I think I prefer @... -

I am reasonably happy with how...
26 Jan 2022

His initial reaction was that he wanted @gens(ideal(L))@ to be an id... -

We can create a zero ideal by supplying an empty list of gens; however, th...

No final d... -

She suggests that they each have... -

So far we had the simple rule that @L = gens(ideal(L))@.
Also the fn *@SyzOfGens@* is defin... -
