18:07 Feature #954: New function: StdBasis (standard basis)
- Fixed a bug (with Robbiano)
-
- Add functions to print resolutions with multigradings and their Betti numbers
(BettiMatrix and BettiDiagram cannot b... -
- I have found the (a?) slow step: there is a call to @saturate(I, ideal(RingElem(RingOf(G),G1)))@ taking a long time.

-
- I cheated: instead of trying to understand XSL I just changed the few "<" into "&lt;".
Works smooothly now.
(... -
- Sometimes a function seeing a list as multiset (and counting the repeated elements) could be useful.
In practice som... -
14:40 Slug #948: radical is slow (compared to singular) on these examples
- Here is another example: CoCoA-5 took about 760s, while Singular took about 0.6s (more than 1000 times faster).
<pr...

- There is a problem for the manual of @StagedTrees@ because there is a "<".
I thought that was sorted out a long time... -

- Which target version were you thinking of?

- What target version do you want for this? 8-O
-
- Check why it isn't yet available: problems for output type in CoCoALib?

- The first example (with 24 indets) was consuming over 7Gbytes of RAM after 15 hours of CPU, so I killed the process (...

- I've just added a first check if the ideal is zero-dimensional.
Thanks to our new MinPoly that is much faster.

- Here is Mario's first example: I have used coeffs in @ZZ/(101)@ but the original was over @QQ@...
-
- Mario gave me two examples where Singular computes the radical *much* faster than CoCoA does.
I'll put the examples ...

- From looking at the code in @BuiltinFunctions-CoCoALib.C@, here is a list of other suspect impls:

- Oh dear! The problem is more widespread. Even @len@ evaluates its arg twice 8-O
-
- Are there any other fns with a similar problem? 8-{
-
- Here is some code we could add to one of the CoCoA-5 tests:...

- Two test cases:...
-
- Having just looked at the code, I'm not entirely surprised.
Also why are there calls to @evalArgAsListOfRingElem@ ... -
- @ideal(RING, func(...))@ evaluates func once,
@ideal(func(...))@ evaluates func twice.

- I have also change the "goodbye pop-up window" in the GUI so that it says "Ciao" instead of "Bye".
-
- This will be a little tricky so postponing.

- Another postponement. It is probably nice for a user to find in a single place a summary of the main quirks/foibles ...
-
- No chance of finishing this is in the near future; postponing by 1 version.
-
- Should there also be an option to say not to use @readline@ even if it is present?
If so, what should the option be ... -
- This issue seems dormant, in reality every time we open a package we clean it up a little bit ;-)
(for example with ... -

- Since the fns which depend on @libblas@ are not documented, perhaps all public versions should be without them (not j...
-
- Postponing again; also lowered priority to *low*.
-
- Postponing because I have no idea how to resolve this (certainly not in the near future).
-
- I am postponing this issue; perhaps I'll wait until it becomes "necessary" for some other task, then decide what to d...
-
- This has been dormant for over two years; should we just close it? I guess Limbeck is/was unable to test it for us.
