16:12 CoCoA-5 Design #782: BuiltinFunctions -- getting too long again!
- (First attempt works, not yet cvs-ed)
Indeed the "cocoa language" file uses directly from CoCoALib just "BigInt".
(in... -
15:17 CoCoA-5 Design #782 (Closed): BuiltinFunctions -- getting too long again!
- Separate into two files functions proper of the cocoa language, and cocoalib functions.
E.g. functions about RECORD ...

23:49 CoCoA-5 Feature #781: Option to "fold" long lines?

This output option would certainly be useful when running CoCoA inside E... -
23:46 CoCoA-5 Feature #781 (Closed): Option to "fold" long lines?
- Emacs becomes very slow when there are long lines in the output.
Consier adding a "fold"-like facility which break...

18:11 CoCoALib Feature #762 (Closed): ExternalLib-GFan: first prototype
- First prototype is done and working!!
Current design is:
- cone functions are in CoCoALib
- GroebnerFan algorithm ... -
18:22 CoCoALib Feature #780 (In Progress): GroebnerFan/ExternalLib-GFan: improve package
- In the package there are lots of operations on integers and those would surely be faster in cocoalib (at some point)....

18:16 CoCoALib Feature #780 (In Progress): GroebnerFan/ExternalLib-GFan: improve package
- First prototype is working.
Investigate and improve it, and implement it in cocoalib.

11:15 CoCoALib Slug #773: DMPZmerge: make non-recursive
- It does! Thanks for the fix!
*NOTE* phew! Thanks for the confirmation :-)

14:20 CoCoALib Slug #773 (Feedback): DMPZmerge: make non-recursive
- I have checked in a cleaned up version of the new code.
I hope Christof will verify that this version is still fine.

13:48 CoCoALib Slug #773: DMPZmerge: make non-recursive
- I can confirm that it is working with your quickly hacked code!

14:41 CoCoALib Slug #773: DMPZmerge: make non-recursive

22:10 CoCoALib Bug #779: Makefile: problem not seeing when files in TmpFactorDir need to be rebuilt
- Since files in @TmpFactorDir@ change very rarely, it is probably not worth fixing the @Makefile@. The time would be ...

22:08 CoCoALib Bug #779 (New): Makefile: problem not seeing when files in TmpFactorDir need to be rebuilt

21:54 CoCoALib Slug #773 (In Progress): DMPZmerge: make non-recursive

20:26 CoCoALib Design #778 (In Progress): CRTMill::myAddInfo accept modulus 1 or not?
- The possible approaches are:
(A) always give error when an input modulus is 1 (but awkward for starting a CRT loop)

20:21 CoCoALib Design #778: CRTMill::myAddInfo accept modulus 1 or not?

-
20:16 CoCoALib Design #778 (In Progress): CRTMill::myAddInfo accept modulus 1 or not?
- Should the mem fn @CRTMill::myAddInfo@ accept a residue-modulus pair with modulus equal to 1?
Such a pair actually a... -
20:04 CoCoALib Bug #776 (Feedback): FloatStr prints a NUL character
- The bug was some overly delicate bug in @ILogBase@ implemented in @BigRat.C@; I had forgotten to allow for possible f...
-
18:42 CoCoALib Bug #776 (In Progress): FloatStr prints a NUL character
- The problem seems to be ILogBase(...,10) giving a wrong result: it gives -9 instead of -10.

22:34 CoCoALib Slug #777: SLUG: elimination

The input is simple, the output not even that large (deg=72)... -

Maybe we could restrict the accepted orderings to j... -
20:15 CoCoALib Feature #775 (New): PPMonoid with 1 extra "exponent"?

20:11 CoCoALib Support #774 (Closed): Rename file PPMonoidEvZZ
- The file @PPMonoidEvZZ@ contains a class called @PPMonoidBigEv@; change the file name?

16:15 CoCoALib Slug #773: DMPZmerge: make non-recursive
- Problem was signalled by email (from Winfried Bruns, Bogdan Ichim on 2015-09-14). It appears to be a stack overflow:...
-
16:14 CoCoALib Slug #773 (Closed): DMPZmerge: make non-recursive
- The fn @DMPZmerge@ is recursive; this is a problem when dealing with large polys.
Rewrite it to be iterative.

12:49 CoCoA-5 Bug #772 (In Progress): Emacs UI: send-region and send-line make sense inside a cpkg5 file?

Point (0): it is correct (and will probably prevail).
Point (1): it will probabl... -
