18:05 Feature #17 (Feedback): implement "binomial" (coefficient) for RingElem: I've made a simple impl (obviously correct, might not be fast).
In answer to my qn in post 2, we've decided to kee... John Abbott

13:08 Design #411: design of factorization template class: I've checked in everything.
For me all tests pass (even with max debugging). Also OK on my linux box (a netbook, >4... John Abbott
12:52 Design #411 (Resolved): design of factorization template class: I have revised the interface of @factorization@.
The 3 main fields are now private, so I have implemented (read-on... John Abbott

15:13 Feature #209: ReadExpr: input polynomials in CoCoALib: *Warning!!*
Syntax for ReadExpr has changed: now the ring is the first argument (looking like RingElem(P, "x")) Anna Maria Bigatti
14:35 Feature #203 (Closed): Function to get the Hilbert Polynomial ring from GlobalManager: working fine for 5 months. closing Anna Maria Bigatti
14:18 Design #411 (In Progress): design of factorization template class: Bite the bullet!
I know what needs to be done; I just have to find the courage to do it (I keep hearing "if it ain't... John Abbott
14:14 Feature #457 (Closed): Zero to the power zero, 0^0: Tidying up; feedback period revealed no problems (in 15 days). Closing.
John Abbott
12:10 Slug #479 (Feedback): make check in examples/ directory is far too slow: Thanks Christof!
I have made the change you suggested, and now it is much faster (5.5s).
John Abbott
11:18 Design #455: Which sets of generators in an ideal?: I think we should have @myMinGens@ in every ideal: a "minimal set of generators" is quite a general concept.
We shou... Anna Maria Bigatti
10:46 Feature #366: function (CoCoALib) for minimal generators (like old Minimalize): What should *minimalize(I)* do?
The cocoa-4 function would create a new ideal (submodule) generated by *MinGens(I)*.... Anna Maria Bigatti

09:34 Feature #482: Unique copies of rings -- smart ctor: My guess is that it will be impossible to deal with under multithreading, and, if implemented, we must guarantee the ... Anna Maria Bigatti

21:28 Feature #482: Unique copies of rings -- smart ctor: If a ring pseudo-ctor is to be smart (and return an existing ring if possible) then how smart should it be?
Consider... John Abbott
21:22 Feature #482: Unique copies of rings -- smart ctor: Having unique copies of rings implies a centralized global registry, and this might adversely affect multithreaded ex... John Abbott
21:12 Feature #482 (In Progress): Unique copies of rings -- smart ctor: After some experience using CoCoALib, it has been useful that @ZZ@ and @QQ@ are unique (_i.e._ repeated calls to the ... John Abbott
21:24 Slug #479: make check in examples/ directory is far too slow: Right now I have only very limited Internet access, so I'm unsure what the current Version of ex-Normaliz does. We wr... Christof Soeger

21:00 Slug #479: make check in examples/ directory is far too slow: The worst culprit is @ex-Normaliz2@ which takes about 90s on my machine -- that's more than half the total time!
T... John Abbott
20:35 Slug #479 (Closed): make check in examples/ directory is far too slow: On my machine @make check@ takes about 160s (not counting compilation!).
That is too slow (especially on my poor lit... John Abbott

00:22 Support #467: Keep CoCoALib web page up to date! All pages!: Far too easy to forget updating EVERY SINGLE PAGE.
I realised that CoCoALib page was still talking about using CoCoA... Anna Maria Bigatti
00:19 Support #467 (Closed): Keep CoCoALib web page up to date! All pages!: Check every so often there is nothing obsolete.
Every single page: sometimes obsolete infos hide in some description... Anna Maria Bigatti

18:13 Support #195 (Closed): OrdvArith documentation needs rewriting: Closing in preparation for new version of CoCoALib.
John Abbott
18:05 Feature #407 (Closed): RingElem ctor from mpz_t (from Bruns): The code has remained unchanged for 4 months, and there have been no problems.
Everyone is happy with the design d... John Abbott
15:26 Feature #459 (New): LinearSimplify: port to CoCoALib: Rewrite @LinearSimplify@ in C++ so it is available in CoCoALib.
John Abbott

17:15 Feature #457 (Feedback): Zero to the power zero, 0^0: Implemented changes to @IntOperations.C@ and @ring.C@ (the old code was buggy).
Added new tests. Modified documen... John Abbott
15:32 Feature #457 (In Progress): Zero to the power zero, 0^0: In an algebraic/combinatorial context it makes sense to define the value of the formula *@0^0@* to be *@1@* even thou... John Abbott
15:14 Feature #457 (Closed): Zero to the power zero, 0^0: After getting "burned" last night when trying to compute *@0^0@* (as an entry in a Vandermonde matrix), I have decide... John Abbott

19:04 Design #455: Which sets of generators in an ideal?: from issue Bug #446: intersection fails with zero ideal

18:57 Design #455 (New): Which sets of generators in an ideal?: now we have
@myGens@
@myTidyGens@
but in SparsePolyRing we would also need

10:06 Feature #209: ReadExpr: input polynomials in CoCoALib: added RingElemInput in documentation (cvs-ed)
(work in progress) Anna Maria Bigatti
10:03 Support #452: Documentation for adding functions to CoCoA-5 (BuiltInFunctions and BuiltInOneLiners): I added an entry to the CoCoALib documentation. (cvs-ed)
Just started
Anna Maria Bigatti
09:31 Support #452 (Closed): Documentation for adding functions to CoCoA-5 (BuiltInFunctions and BuiltInOneLiners): Code is very readable, but some documentation would be nice, wouldn't it?
*2014-07* the documentation is in doc/tx... Anna Maria Bigatti

17:10 Feature #426: ConvertTo with optional arg to give more helpful error message: added example and documentation (cvs-ed) Anna Maria Bigatti
16:30 Feature #426 (Feedback): ConvertTo with optional arg to give more helpful error message: Jon implemented this and forgot to say it?
anyway it is very nice:
