- 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??? - 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...

- 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). ... - 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...

- Giulia has done 4 examples.
For next time she will convert the code in the solutions into various functions (_e.g._ ... - 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...

- 11:34 CoCoA-5 Feature #19 (Closed): How to get the version number of CoCoA-5?
- 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...

- Here is note for accumulating ideas for structuring CoCoALib exceptions:
(1) create _CannotDivide_ which has two sub... - 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@...

- Currently the function
@bool IsDivisible(ConstRefRingElem num, ConstRefRingElem den)@
returns *false* if den=0.

- 17:14 CoCoALib Feature #221 (Resolved): Better RingElems
- Updated the doc for RingElem.
Might be necessary to revise the example progs?
- 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...
