- 23:50 CoCoA-5 Slug #875 (In Progress): Interpreter is too slow reading a big polynomial
- I have taken one of Mario's big polys: this one is about 6Mbyte when printed out.
I tried to ways of converting th... - 21:58 CoCoA-5 Slug #875: Interpreter is too slow reading a big polynomial
- The solution to use @ReadExpr(P, "poly-as-a-string")@ works tolerably well from the point of view of the interpreter,...
- 15:37 CoCoALib Feature #206: Matrix equation solving: LinKer
- For aesthetics: now changes sign to the LinKer matrix (so that the entries corresponding to the "pivots" are "1" inst...

- 17:01 CoCoALib Slug #881: ReadExpr is too slow on large polys
- Using the profiler on a linux box I noticed that @DistrMPolyInlPP::myPushFront@ was using surprisingly much time. I ...
- 16:57 CoCoALib Feature #885: IsIrred3: fast 3-way irred test (returning bool3)
- The idea of @IsIrred3@ was created because of some computations Mario needed to do with multivariate polynomials, so ...
- 11:13 CoCoALib Feature #885 (In Progress): IsIrred3: fast 3-way irred test (returning bool3)
- Some questions:
* *(A)* what should the function be called? Is @IsIrred3@ a reasonable name?
* *(B)* what should t... - 16:49 CoCoALib Design #846: IsIrred: correct design?
- The simplest design is to make @IsIrred@ call @IsIrred3@; this somehow equates calling @IsIrred3@ to handling the tri...
- 13:43 CoCoALib Design #846 (In Progress): IsIrred: correct design?
- I think a first version of @IsIrred@ should give error if the ring is a field; if it turns out that this is inconveni...

- 17:27 CoCoALib Feature #885 (In Progress): IsIrred3: fast 3-way irred test (returning bool3)
- Implement an irreducibility test @IsIrred3@ which is guaranteed to be fast, but returns a @bool3@.
- 15:25 CoCoALib Slug #884: DistrMPolyInlPP::myPushFront and DistrMPolyInlPP::myPushBack inefficient if arg is a PP
- I wrote a special reading fn for polynomials (using a "private" linearization). It was not as fast as I hoped, and p...
- 15:20 CoCoALib Slug #884 (New): DistrMPolyInlPP::myPushFront and DistrMPolyInlPP::myPushBack inefficient if arg is a PP
- In the class @DistrMPolyInlPP@ the mem fns @myPushFront@ and myPushBack@ can accept raw coeff and raw pp, *BUT* the i...

- 14:48 CoCoALib Slug #881: ReadExpr is too slow on large polys
- I reran the test to read Mario's polynomial: now it takes about 0.4s (with the "wrong" term-ordering), and about 0.25...
- 14:32 CoCoALib Slug #881: ReadExpr is too slow on large polys

- 12:09 CoCoALib Slug #881: ReadExpr is too slow on large polys
