13:57 Feature #876 (New): subst: allowed also for indets in the coeff ring: Suppose we have a poly ring of the form @QQ(a,b)[x,y]@ and I want to substitute @b=a+1@.
Currently @subst@ refuses b... John Abbott

17:02 Slug #875: Interpreter is too slow reading a big polynomial: I have tried doing some profiling. The interpreter takes quadratic time (in the number of terms) to read a polynomia... John Abbott
14:00 Slug #875 (In Progress): Interpreter is too slow reading a big polynomial: I'm trying to read a large polynomial: about 6Mbytes, about 127000 terms in 100 indets, coefficients in @QQ@ (but all... John Abbott

19:05 Bug #870: GBasis of product of ideals is wrong (Vadim Tropashko) --> I.myReset(): I have added a new CoCoALib test (@test-bug6.C@) which tests for this specific problem.
It should later be expande... John Abbott

done! (cvs-ing)

15:19 Bug #870: GBasis of product of ideals is wrong (Vadim Tropashko) --> I.myReset(): I suggest that Anna try to fix the functions already in @SparsePolyRing.C@.
Even though I'm hoping for a proper re... John Abbott
13:38 Bug #870: GBasis of product of ideals is wrong (Vadim Tropashko) --> I.myReset(): I continue to think that the current design of ideals is completely wrong (but I cannot find the redmine task about t... John Abbott
10:16 Bug #870 (In Progress): GBasis of product of ideals is wrong (Vadim Tropashko) --> I.myReset(): Here is the equivalent CoCoALib code -- it exhibits the problem.... John Abbott
09:39 Bug #870: GBasis of product of ideals is wrong (Vadim Tropashko) --> I.myReset(): Try looking around @SparsePolyRing.C:2029@

09:35 Bug #870: GBasis of product of ideals is wrong (Vadim Tropashko) --> I.myReset(): Since this was reported by a CoCoA-5 user i have put it in the CoCoA-5 category even though I'm almost certain that t... John Abbott
09:31 Bug #870 (Closed): GBasis of product of ideals is wrong (Vadim Tropashko) --> I.myReset(): Vadim Tropashko reported an incorrect result. Robbiano has simplified it. Here is the simplified version.... John Abbott

12:38 Design #868: Der, Bin: why the capital letter?: It is also the case for @bin@.
In CoCoALib they are called @deriv@ and @binomial@, so the lower-case name is differe... Anna Maria Bigatti

20:06 Bug #287: --fullCoCoALibError prints too much (Try/UponError): I still like my proposal in comment 2. How easy it will be to implement is not clear to me.
Anyway the implementa... John Abbott
20:00 Design #868: Der, Bin: why the capital letter?: I understand we want to keep @Der@ for backward compatibility.
Since we have @deg@, @den@, @det@ why not also @der... John Abbott
19:59 Design #868 (Closed): Der, Bin: why the capital letter?: In CoCoA-5 the function for computing formal derivatives is @Der@; why does @der@ not exist?

18:00 Bug #287: --fullCoCoALibError prints too much (Try/UponError): Ooops, apparently I released the Mac version of cocoa-5.1.4 with the flag activated.
This means that users computing... Anna Maria Bigatti

13:22 Feature #865 (New): Implicit: make easier to use with rational functions: Make the CoCoA-5 interface (also CoCoALib interface?) easier to use when the parametric descriptions are as rational ... John Abbott
