18:24 CoCoALib Bug #277 (New): Eliminate class RefPPMonoidElem?: Recently I eliminated the class @RefRingElem@ for ring elements.
Should I do the same for *@RefPPMonoidElem@*?
Pres... John Abbott

15:00 CoCoALib Feature #127 (In Progress): Convert DUPFF code to C++: JAA has written a first prototype.
It works, but is 10% slower than the old C code for multiplication - why??? John Abbott
12:45 CoCoALib Feature #144 (Resolved): Buchberger-Moeller: generic impl: JAA has implemented a first prototype in CoCoALib.
It works on two simple examples. Still need to:
* make it accessi... John Abbott

09:49 CoCoA-5 Feature #78: Elim ordering and matrix ordering in CoCoA-5: *CompleteToOrd* gives a non-term-ordering if there are 0's in the given row.
I think it's easy to fix (in cocoalib). ... Anna Maria Bigatti
09:10 CoCoA-5 Feature #276 (New): TeXmacs interface: We still have problems about the graphical interface.
Can we easily get a nice interface with TeXmacs?
possibly usi... Anna Maria Bigatti

15:51 CoCoA-5 Feature #273 (In Progress): Package for Polynomial Algebra Homomorphisms: Giulia has done 4 examples.
For next time she will convert the code in the solutions into various functions (_e.g._ ... John Abbott
10:42 CoCoALib Feature #121: Porting "IdealOfPoints": I think that the good old code should be linked first.
Making a proper clean Chinese Remaindering in CoCoALib will r... Anna Maria Bigatti

18:46 CoCoA-5 Bug #275 (Closed): Unhelpful error messages when SmallExponent_t is unsigned char.: I changed @config.H@ so that the type @SmallExponent_t@ is @unsigned char@ (in an attempt to tackle Enrico Carlini's ... John Abbott

14:01 CoCoA-5 Feature #274: InputForm for output readable as input: We should probably avoid the name *@InputForm@*; in the past the people behind Mathematica have not hesitated to sue ... John Abbott
11:14 CoCoA-5 Feature #274 (In Progress): InputForm for output readable as input: Compare these... Anna Maria Bigatti
11:37 CoCoA-5 Feature #212 (Feedback): NBM: add to CoCoA-5: Anna Maria Bigatti
11:34 CoCoA-5 Feature #19 (Closed): How to get the version number of CoCoA-5?: Anna Maria Bigatti
11:30 CoCoA-5 Bug #192 (Closed): indent prints strings without quotes: Apart from quotes inside strings it works.
I don't think it is very useful, but because of that I cannot consider th... Anna Maria Bigatti

15:59 CoCoA-5 Feature #273: Package for Polynomial Algebra Homomorphisms: Giulia will do "by hand" some of the examples from Robbiano's book so that she better understands what are the diffi... John Abbott
15:31 CoCoA-5 Feature #273 (Closed): Package for Polynomial Algebra Homomorphisms: Giulia Bianco is studying the implementation of various operations on homomorphisms of polynomial algebras.
The re... John Abbott

14:17 CoCoALib Feature #92: Error Codes: BadIndex: Here is note for accumulating ideas for structuring CoCoALib exceptions:
(1) create _CannotDivide_ which has two sub... John Abbott
13:55 CoCoALib Feature #248: IsDivisible for RingElem with nice interface: The main question is precisely when should @IsDivisible@ return false?
Assuming @x,y,z@ are all @RingElem@...
(A)... John Abbott
13:34 CoCoALib Feature #248: IsDivisible for RingElem with nice interface: Currently the function
@bool IsDivisible(ConstRefRingElem num, ConstRefRingElem den)@
returns *false* if den=0.
I ... Anna Maria Bigatti

17:14 CoCoALib Feature #221 (Resolved): Better RingElems: Updated the doc for RingElem.
Might be necessary to revise the example progs?
John Abbott
17:13 CoCoALib Feature #261 (Resolved): Review the utility of RefRingElem: I have updated the doc for RingElem and friends.
It probably needs some more work, but I'm taking a rest over the we... John Abbott
