16:57 Feature #1001 (In Progress): CoCoALib: ideas for student projects

Suggestion: *split the 2 issues into: ones for CoCoA-5, and ones for CoC... -
15:32 Support #467 (Closed): Keep CoCoALib web page up to date! All pages!

Checked in. Hoping it... -

- This issue overlaps with Feature #1598.
17 Feb 2022
-
- I have now removed @apply@ from all the packages as well... sigh!
All tests pass now. -
- I have now made @apply@ obsolescent, and updated the doc.
Hopefully all is OK now... I'd better run the tests (sigh... -

then the question about permutations goes away.

-
-
- Closing this issue. Created new issue for the generalization: #1668
-
- Generalize the function *@prim@* (see #1580).
Let it work in "towers" of extensions (where that makes sense).
-
- I have just searched quickly for doc about the mem fns for sending OpenMath serializations, but found nothing.
The g... -
- I think this is largely automatic now.
Can we close?

Also make several algorithmic improvements... -

Oh joy! That C++ has inherited so many "complicated/confusing" integer types...

-
- Mac and Linux now done. I made a new issue for windows/cygwin #1665
14 Feb 2022
-
- All done. Closing.
-
- This is effectively superseded by issue #1591.
Closing -- the info here seems rather out of date.
-
-
- I don't want to make hasty decision now, so this ("division related") is the state for release 0.99720.
Postponing... -

Changed version numer to 719 (very close to the official 720)

Instructions are good.

Any chance of getting the doc sorted out?

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.

-
- *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@?

- 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.
02 Feb 2022

- There is probably an implementation in the "Gbasis over ZZ" package: see issue #1272.
