23:31 Feature #437: MemPool: order free blocks?
- I have just looked at some stats about @MemPool@ in one very particular example, and now wonder whether sorting the e...

23:25 Feature #681: MemPool: make it easier to get just stats
- Currently it is possible to get some stats reports from @MemPool@ objects by doing all of the following:
* @MemPoolD... -
23:20 Feature #681 (New): MemPool: make it easier to get just stats
- I wanted to get some usage stats from @MemPool@ objects; it was not as easy/helpful as I would have liked.

22:22 Bug #680: DistrMPolyClean does not use MemPool for summands?
- Why is the @MemPool@ object which is given to @DistrMPoly@ ignored?
MemPool logging shows that the summand pool is... -
22:18 Bug #680 (Resolved): DistrMPolyClean does not use MemPool for summands?
- It seems that @DistrMPolyClean@ does not use @MemPool@ for summands even though a suitable @MemPool@ as passed as arg...

15:01 Slug #679: power for PPs is too slow
- I have implemented a first version. All tests pass. Still needs cleaning; must update doc. I'll pass prototype to ...

14:59 Slug #679: power for PPs is too slow
- The proposed design is for each @PPMonoid@ to offer 2 fns:
* @myPower@ which just computes the power *without checkin... -
14:54 Slug #679 (Closed): power for PPs is too slow
- Profiling showed that powering PPs incurred a significant time penalty in the (prototype) code for @ImplicitDirect@.

21:46 Feature #678: Accumulator (like a geobucket)
- Note: perhaps also consider the design of C++ @std::accumulate@? Is there anything in BOOST?
My (vague) idea is t... -
21:36 Feature #678: Accumulator (like a geobucket)
- I have just written @DetDirect@ which computes the sum of many terms (one for each permutation). In order to get dec...

21:30 Feature #678 (In Progress): Accumulator (like a geobucket)
- Consider creating a general "accumulator" for ring elems, a sort of generalization of a geobucket.

09:18 Slug #675: Matrix determinant over multivariate poly ring
- In my specific instance the direct algorithm (as alternating sum of products) would be best.
The problem with mult... -
09:16 Slug #675 (In Progress): Matrix determinant over multivariate poly ring
- CoCoA can be too slow and require too much RAM for computing determinant of a matrix of multivariate polynomials.

11:53 Bug #15: Adjoint of a non-invertible matrix
- I am planning to implement a direct algorithm: each entry in the @adj@ is just a determinant, and each determinant is...

15:59 Bug #15: Adjoint of a non-invertible matrix
- Even @AdjByDetOfMinors@ takes too long for a 6x6 matrix of distinct indets. Why?
*2015-03-26 NOTE* I think the prob... -
15:22 Bug #15: Adjoint of a non-invertible matrix
- @adj@ is a very simple function: it chooses between @AdjByDetOfMinors@ and @AdjByInverse@.
What do you think @AdjB... -
14:52 Bug #15 (In Progress): Adjoint of a non-invertible matrix
- I do not recall when, but @adj@ has aleady been added to CoCoALib.
It has a *VERY BAD SLUG*: even after several mi...
