16:48 Bug #756 (Closed): frobby (v0.9.0) does not compile with g++-4.8
JAA has a temporary version of FROBBY available in @frobby_v0.9.3.tgz@
This seems to avoid the portability problem...
John Abbott
16:43 Bug #975: configure: possibly ignore GMP compilation flags
I have made a preliminary version of @configure@ and various auxiliary scripts which do not expect extra CXXFLAGS for... John Abbott
15:53 Feature #1035 (Closed): Improvement: how to sort QuotientBasis?
John Abbott
15:50 Feature #1102 (Closed): Implement RootBound
John Abbott
15:49 Feature #255 (Closed): Use BOOST lib default location if possible
JAA thinks this has already been resolved adequately in the intervening 5 years.
Closing.
John Abbott
15:31 Feature #796 (Closed): CoCoALib function for radical (or SqFree) of a polynomial
OK, let's use *@radical@* then (both for ideals and ring elements); it is the clearest.
Closing.

14:24 Feature #796: CoCoALib function for radical (or SqFree) of a polynomial
It seems that this issue is practically finished except for the questoon of the name of the function.
The main choic...

15:27 Feature #1108 (Closed): New fn: IsCoprime (whenever gcd makes sense)
John Abbott
15:24 Support #574 (Resolved): Tidy CoCoA root directory
I think this has been mostly done.
There is no longer the GPLv2 file, no any file called @INSTALL@ (but there is @...
John Abbott
15:15 Slug #1042 (Closed): LF curiously slow (breaking a poly into homog pieces)
John Abbott
15:12 Feature #979 (Closed): SmallestNonDivisor -- new fn
This is apparently complete (also included in CoCoA-5).
John Abbott
15:06 Bug #1101 (Feedback): Bug in MinPolyModular (insufficient rational reconstruction)
John Abbott
14:41 Feature #37: matrix constructors
*MatByRows/Cols* is now available in CoCoALib.
All other questions have been dealt with, more or less directly.

14:31 Feature #37: matrix constructors
This issue is a bit strange -- it is now quite old, and of questionable relevance now.
Perhaps we should just clos...

14:06 Feature #730 (Feedback): Stats in GBMill (GReductor)
John Abbott
13:56 Slug #881 (Feedback): ReadExpr is too slow on large polys
John Abbott
13:48 Feature #962 (Feedback): General verbose mode?

12:38 Bug #1113: gcd crashes (Floating point exception)
Here is another example (possibly simpler than the previous one?):... John Abbott

13:19 Feature #1115 (In Progress): New class: exterior algebra
Add this new class, mimicking @RingWeyl@.

15:36 Slug #1105: Primary Decompositon (zero-dim) slow cases
Here are some examples I found lying around in a file:... John Abbott

17:45 Bug #1113 (Closed): gcd crashes (Floating point exception)
In an old file (from 2006) I found two examples where GCD (in CoCoA4) crashes because it runs out of primes; since we... John Abbott
11:53 Design #703: Add more operations between modules (CoCoALib)
Reminder. Add +. Anna Maria Bigatti

25 Oct 2017

13:29 Slug #1110 (Closed): Determinant of matrix over QQ (whose entries are actually integers)
CoCoA-5 can be much faster as computing @det(M)@ if @RingOf(M)@ is @ZZ@ than the same matrix but over the ring @QQ@.

17:15 Feature #1108 (Resolved): New fn: IsCoprime (whenever gcd makes sense)
I have written a first trivial implementation. Seems to work.
John Abbott
16:50 Feature #1108: New fn: IsCoprime (whenever gcd makes sense)
The fn should be defined when *@gcd@* makes sense (_i.e._ for true GCD domains and @BigInt@).
At the moment I pref...
John Abbott
16:48 Feature #1108 (Closed): New fn: IsCoprime (whenever gcd makes sense)
Define a new fn *@IsCoprime@* which is equivalent to *@IsInvertible(gcd(arg1, arg2))@*
JAA thinks it is better to ...
John Abbott
15:47 Feature #630 (Feedback): Add graeffe function?
Added code; doc; example.
Also made accessible to CoCoA-5.
John Abbott
