- 17:03 Slug #798: use poly ring with many variables is too slow
- In @PolyRing.H@ there is a fn called @IndetSymbol@ which apparently gives the symbol of the @k@-th indet. Presumably...
- 15:02 Slug #798: use poly ring with many variables is too slow
- Functions involved include:
@RING::injectIndeterminates@ in @Interpreter.C:456@ which calls
@allSymbolValues@ in @Int... - 13:52 Slug #798: use poly ring with many variables is too slow
- I was forgetting that the @use@ command in CoCoA-5 also assigns all the CoCoA-5 variables whose names coincide with t...

- I have just tried @NewPolyRing(RingQQ(),10000)@ in CoCoALib, and it took just 4s.
So why so much slower in CoCoA-5?
... - 11:41 Slug #798: use poly ring with many variables is too slow
- I suspect the main problem is that creating a poly ring also creates a @std::vector@ containing each power-product as...
- 11:38 Slug #798 (Closed): use poly ring with many variables is too slow
- Mario will need polyrings with many variables (>10000).
CoCoALib seems to have no "artificial limit"; but when I tri... - 15:29 Feature #451 (In Progress): Port function NewSymbol/NewSymbols to CoCoA-5
