Description

Application of PolyAlgebraHom can be unreasonably slow (this is indeed a problem in optimizing multivariate evaluation)

History

#1 Updated by Anna Maria Bigatti about 9 years ago

We found this slug while workig on Implicit (evaluation for checking the final output can be very slow)

#2 Updated by Anna Maria Bigatti about 9 years ago

I thought that it could be improved using geobuckets, so I searched the actual code performing the computation.
It is ApplySPRCodomain in SparsePolyRing.C.... and yes: it is already using geobuckes :-(
