- 14:26 Bug #1171: RealRoots: first point is sometimes wrong?
- I suggest a function with the following semantics:
* call *RealRootsSmallValue(f, eps)*
* result is a list of close... - 14:19 Bug #1171: RealRoots: first point is sometimes wrong?
- It is not as simple as I first thought. While the first order approximation I mentioned in comment 3 is correct, it ...

- The intersection of MODULEs need to be exported.
- 09:26 Feature #1174 (Closed): package of a function --> of an identifier!
- How to have a function that says in which package is in the input?
Why does not describe have this feature?!

- 14:31 Bug #1172: MinSubsetOfGens: problem with generators = 0
- Fixed @GPolyList EmbedVectorList(const VectorList& theVL, const GRingInfo& theGRI, const long StartingFromCompIndex)@...
- 12:27 Bug #1172: MinSubsetOfGens: problem with generators = 0
- The problem is actually in @GBasis(M)@ when gens(M) contains a 0 element.
Fixing...
- 12:05 Bug #1172: MinSubsetOfGens: problem with generators = 0
- which package?
- 09:30 Bug #1172 (Closed): MinSubsetOfGens: problem with generators = 0
- In case of type MODULE there is:
J := submodule(ModuleOf(X), WithoutNth(L,I));
but it does not allow to v... - 11:34 Bug #1171 (In Progress): RealRoots: first point is sometimes wrong?
- One can estimate the "stability" of the root by computing the value of the derivative at that root. By Taylor expans...

- 18:57 Bug #1171: RealRoots: first point is sometimes wrong?
- It seems that actually the problem is in the instability of the roots: the approximate root is probably close to the ...
- 18:27 Bug #1171: RealRoots: first point is sometimes wrong?
- I found this bug while debugging @ApproxSolve@.
I had noticed that, when the answer was wrong, it was just on the fi... - 18:25 Bug #1171 (Closed): RealRoots: first point is sometimes wrong?
- It seems that sometimes (very rarely) the first root given by @RealRoots@ is wrong...

- 19:01 Slug #948: radical is slow (compared to singular) on these examples
- All 0-dimensional ideals (i.e. those in x,y,..), now take less than 1 second.
I have added (as John suggested) a tim... - 09:07 Slug #948: radical is slow (compared to singular) on these examples
- (just to know, when testing)
All these examples in "c" have positive dimension.
All these examples in "x" are 0-dim... - 16:59 Slug #1114 (Closed): Some other examples for 0-dim radical
