Thanks, Dima! The SINGULAR package does the classical resolution algorithm well. Jonghyun, the student, is reading the developer Anne Frühbis Krüger's extensive texts about it. The new algorithm uses in part the same objects.
So as you say, it might make sense to move over to SINGULAR. - Dan On Friday, August 23, 2019 at 3:11:05 AM UTC-4, Dima Pasechnik wrote: > > On Fri, Aug 23, 2019 at 3:55 AM Dan Abramovich <dan_abr...@brown.edu > <javascript:>> wrote: > > a student of mine, Jonghyun Lee, will be coding the resolution of > singularities algorithm of the > > > > paper > > > > > > https://arxiv.org/abs/1906.07106 > > > > > > as part of his senior thesis.
