- 17:43 CoCoALib Feature #1819 (In Progress): New functions in CoCoALib using GBasisTrunc: MinSubsetOfGens, IsContainedTrunc, ..

- 17:22 CoCoALib Bug #1740 (Resolved): MinGens gives non minimal gens *if some deg=0*
- A clever implementation is difficult/impossible.
However, the new @GBasisTrunc@ (which also works for non-negative g... - 11:33 CoCoALib Bug #1740: MinGens gives non minimal gens *if some deg=0*

- There was a bug in GBasisTrunc, now fixed.
These functions are in CoCoA-5. Port them to CoCoALib:

- Resolved using truncation (works also for non-negative gradings)

- When we multiply or divide a polynomial by a coefficient, we can use myMulByCoeff/myDivByCoeff.
This is actually che... - 17:41 CoCoALib Design #1689: Automatic mapping of RHS in += etc
- Is this valid now? something along this lines is valid.
- 14:39 CoCoALib Design #1744: Implement GBMill (aka Groebner Framework)
- First step would be to kill definitely all the code for the dynamic GBasis.
It is sad to do so, but I have no idea h... - 14:12 CoCoALib Design #1744: Implement GBMill (aka Groebner Framework)

I... - 14:11 CoCoALib Feature #1743: Implement Truncated GBases for homogeneous input
- MinGens now truncates to the max degree of the generators.
Can be considerably faster than before, of course.
- 14:09 CoCoALib Feature #1743: Implement Truncated GBases for homogeneous input
- Implemented.
Meanwhile I made a few tiny changes in the direction of the Framework/Mill.
Tested, seems fine.
Now...
