10:21 Slug #907: ApproxSolve very slow on this example
- This is another example where @ApproxSolve@ is too slow (in CoCoA-5.2.2).
The example came from "playing with" palin...

17:22 Slug #948: radical is slow (compared to singular) on these examples
- Singular appears not to compute a GBasis for the radical.
For instance, in the first example in comment 11, Singul...

18:00 Design #476 (In Progress): Review utility of package IO
- Indeed some form of "folded" printing could be useful for large outputs (especially inside emacs which has problems w...

14:30 Slug #948: radical is slow (compared to singular) on these examples
- I have noticed that when I interrupt the very long radical computations the interpreter indicates that it was computi...

17:21 Slug #948: radical is slow (compared to singular) on these examples
- Here is another slow example: (about 450s on my computer)...

14:43 Slug #948: radical is slow (compared to singular) on these examples
- I have just tried the last example (916s) from the comment above modulo 32003 and modulo 29641. The computation was ...

13:43 Bug #1100: PrimaryDecomposition0: says not 0-dim but IsZeroDim says ideal is zero-dim!
- Here is a zero-dim ideal with primdecomp having 32 components:...

12:20 Bug #1100: PrimaryDecomposition0: says not 0-dim but IsZeroDim says ideal is zero-dim!
- Anna: have you added the example(s) as a tests cases in the CoCoA test suite?

19:19 Bug #1100 (Feedback): PrimaryDecomposition0: says not 0-dim but IsZeroDim says ideal is zero-dim!
- Fixed: was a problem in @MinPolyModular@.

18:40 Bug #1100: PrimaryDecomposition0: says not 0-dim but IsZeroDim says ideal is zero-dim!
- Found it: we knew it could happen, and this is the first time I see it!
The modular reconstruction gives the wrong... -
18:21 Bug #1100: PrimaryDecomposition0: says not 0-dim but IsZeroDim says ideal is zero-dim!
- With SetVerbosity(90) it appears that down in the recursion it get an ideal=(1).
Investigating (should never happen!)

14:39 Bug #1100 (Closed): PrimaryDecomposition0: says not 0-dim but IsZeroDim says ideal is zero-dim!
- Bug summarized in this transcript...
