- I have now revised the impl after designing a simple test, and seeing that the behaviour was "sub-optimal"...
The te... - 08:47 Support #1298 (Resolved): How can user find the indent command?
- I have removed the example of @indent@ with 2 args; I really this it makes the manual page more readable.
I have cha... - 08:35 Slug #1581 (New): Slow sqfr: rad(f)
- This poly arises in the first computation from issue #948.
CoCoA takes too long to compute its radical:... - 08:11 Slug #948: radical is slow (compared to singular) on these examples
- The examples in comment 13 are now reasonably quick.
The one in comment 2 is still slow -- *cause is* trouble with m... - 07:59 Bug #1502: SystemCommand in Microsoft version

By chance I happened to speak to a friend (Nick) who suggested ... - 07:56 Design #1554: cocoa5-emacs-dir or cocoa5-root-dir?

- 23:03 Feature #1536 (Feedback): Implement xel?
- I have added doc, but no tests (too lazy/tired).
- 22:00 Feature #1536: Implement xel?
- Anna has too much else to do. So I have knocked up a quick impl... brain off, just cut-and-paste... and hope!
Per... - 20:47 Bug #1171: RealRoots: first point is sometimes wrong?
- We could try to mimic the hack described in issue #1573, where the values are checked at the approx solutions, and re...
- 20:31 Support #911: CoCoA-5 prompt for incomplete input
- I am not convinced of the utility of the dot-dot-dot when the supplementary prompt is non-empty.
It is hard to expla... - 20:27 Support #911: CoCoA-5 prompt for incomplete input
- The supplementary part of the prompt comes from *@openBlocks@*.
I have no idea how the value of @openBlocks@ is upda... - 20:25 Support #911: CoCoA-5 prompt for incomplete input
- Here is what my personal CoCoA does currently:...
- 17:31 Support #911: CoCoA-5 prompt for incomplete input

I also wonder whether the case of a prefix cont... - 17:21 Feature #500: Interpreter: is it possible to avoid useless prompts?

- 17:26 Bug #1577 (Resolved): radical: lex order, ERROR: Ring is not standard graded
- Anna has implemented the obvious workaround: map into a new poly ring (with degrevlex), and then unmap the result.
S... - 17:00 Bug #1396 (Resolved): Website: download page for CoCoA-4 burns CPU
- Anna removed some Java script... now seems OK.
- 09:50 Feature #1112: New function: IsEmpty
- The function *@IsEmpty@* is slower than explicitly testing for equality to the empty list; why should that be?
He...

- 22:18 Feature #1112 (Resolved): New function: IsEmpty
- I have just added a first impl to @BuiltInFunctions.C@.
A couple of trivial tests passed.
Still need to: write te... - 22:07 Feature #250 (Feedback): CoCoALib BuildInfo vs CoCoA-5 VersionInfo
- The code in @VersionInfo.C@ looks clean and simple to me.
I think this issue has been resolved some time ago.
Movin... - 22:05 Bug #1396: Website: download page for CoCoA-4 burns CPU
- The problem still exists :-(
- 22:03 Design #474: Eliminate package BinRepr
- It looks to me as though this could easily be converted into C++ (in CoCoALib).
Perhaps just an afternoon suffices..... - 22:00 Bug #1215 (Feedback): RationalSolve: gives "Error: must be non-zero"
- Is this issue a *duplicate* of issue #724?
I think so. Anyway, I tried the example mentioned in the description, an...

We must develop a proper test s... - 18:33 Design #1540 (Resolved): Double power

- 14:41 Bug #946: Function "ideal" evaluates the argument twice
- I might have fixed this (for ideals)... and probably introduced some new weird bugs.... the interpreter code is not e...
- 14:09 Slug #1392 (Resolved): ApproxSolve: another slow example
- The example given is quite quick now (0.5s on my computer).
Marking as "resolved" (don't know by whom or when).
- 14:04 Bug #1574: ApproxSolveTF
- The code seems to be a bit convoluted. It'll take time to work out what it is supposed to be doing... not today!

12 Feb 2021
- 12:19 Bug #724 (Resolved): RationalSolve: wrongly complains about non zero-dim even in finite char
- The example from issue #723 is way too slow to act as a test case -- do we have a more sane test case? How about the...
- 12:16 Feature #723: Referring to indets with multiple indices from a polyring
- The example in comment 2 is slow because it takes along time to test @IsZeroDim@ _i.e._ compute a GB.
I stopped th... - 11:54 Slug #1270 (Feedback): RationalSolve: use MinPolyQuot instead of elim
- I have just tried the example from comment 5, and @RationalSolve@ is now tolerably fast (less than 2s).

- 00:13 Support #1252: ShapeLemma: no manual entry
- What is the status of this issue?
- 00:12 Bug #1573 (Resolved): ApproxSolve: very imprecise

If the values are not "heur... - 00:08 Bug #1216 (Feedback): RationalSolve: gives wrong answer

It may be sensible to use different names for th... - 20:50 Bug #1216: RationalSolve: gives wrong answer

Now I must impl, and revise th...
