- 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
- I have now rewritten the hacked code in a cleaner way, but shall still wait for confirmation from the Normaliz group ...

- 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
- I have had a "quick hack" at the code. The CoCoA/CoCoALib tests all pass, but I'm not sure that any of them actually...
- 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.

The input is simple, the output not even that large (deg=72)... - 22:31 CoCoALib Slug #777 (In Progress): SLUG: elimination

- It might be worth offering a @PPMonoid@ whose internal repr for a PP contains an expv and one extra @long@.
If the... - 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.

Point (0): it is correct (and will probably prevail).
Point (1): it will probabl... - 12:21 CoCoA-5 Bug #772: Emacs UI: send-region and send-line make sense inside a cpkg5 file?

I already have (simple) implementations in my own personal copy of @list.cpkg5@.
If we wa... - 15:58 CoCoA-5 Feature #771 (Closed): New fns: MaxBy and MinBy to find minimum/maximum of a list wrt a given order

- 20:14 CoCoALib Design #769: CoCoALib cone
- Anders pointed out that normaliz's interpretation of "const" is probably more threadsafe than gfan's

A CoCoALib cone object typically contains both a normaliz cone and a gfan cone. Obvio... - 15:19 CoCoALib Design #769: CoCoALib cone
