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...

19:03 Bug #946: Function "ideal" evaluates the argument twice
- I have just checked in my revised code (even though it still needs to be cleaned).
We must develop a proper test s... -
18:33 Design #1540 (Resolved): Double power
- I think I have solved the main problem and also the one mentioned in comment 2.
Solution is not elegant, but I do no...

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!

22:20 Bug #1567 (Feedback): Radical in non-zero char
- I have check in the changes (some time ago). So moving status to _feedback_.

-
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
- I have now added an extra loop which checks the values of the polys at the points found.
If the values are not "heur... -
00:08 Bug #1216 (Feedback): RationalSolve: gives wrong answer
- I have implemented the new field names, and updated doc, tests, manual.
New state: Feedback. -
17:56 Bug #1216: RationalSolve: gives wrong answer
- > Possible names are *@AffinePts@* and *@ProjectivePts@* (or *@ProjPts@*).
I vote for *@AffinePts@* and *@Projecti...

- Feedback and constructive criticism are welcome!
I'd like to close this issue soon.
-
21:28 Bug #1216: RationalSolve: gives wrong answer
- Now I wonder what the names of the fields in the records should be.
It may be sensible to use different names for th... -
20:50 Bug #1216: RationalSolve: gives wrong answer
- Anna has approved the suggestion in comment 13 (just above) about returning a record.
Now I must impl, and revise th...

15:22 Bug #727: Emacs UI: send-file (C-c C-f) should check if buffer and file are synchronized

I have searched on internet, but there does not seem to be an eas...

17:48 Bug #1574: ApproxSolveTF
- I have set the target version as 5.3.6, but maybe it could be postponed?
It is a bit strange that the solution [0,... -
17:46 Bug #1574 (New): ApproxSolveTF
- @ApproxSolveTF@ is not documented. Maybe that is a good thing......

17:26 Bug #1216: RationalSolve: gives wrong answer
- I now think it might be better to avoid the "clever" function @RationalSolve@ which tries to guess whether it should ...
