This is an interesting promotion of an applied math result. From their promotional material it looks promising, though the unusual promotional approach makes me worry.
The actual paper is at https://www.sciencedirect.com/science/article/pii/S0166531619302457/pdfft?md5=7de20355de7ca3e047e645006fa812f2&pid=1-s2.0-S0166531619302457-main.pdf https://www.sciencedirect.com/science/article/pii/S016653161.... This is a pretty obscure journal. The paper is pretty "soft" -- lots of numerical testing of their approach vs. other well-known approaches and not very much theoretical analysis of convergence rates or such.
The main claim seems to be that their approach has better numerical properties for discontinuous functions and that it can be effectively implemented to high order using double precision arithmetic.
- mratsim 6y agoI'd rather have an applied paper have tests, comparisons and source code than lots of theory and being hard to reproduce because "implementation details" don't appear in the paper. Thanks the authors for putting the code out there for anyone to reproduce and not fall into the unreproduceable "science" that is plaguing us at the moment[1].

- JorgeGT 6y agoWhy do you say they are not associated? They seem part of a research group of the Technical University of Budapest, looking at the papers affiliations. As a researcher I really appreciate the promotion effort, some years ago I came across a similar "landing page" for a numerical technique that helped me a lot: http://people.ece.umn.edu/users/mihailo/software/dmdsp/ http://people.ece.umn.edu/users/mihailo/software/dmdsp/, Trying to put together how a new numerical method works scouring for papers with different nomenclatures, different sets of authors, different implementations etc. is often a huge pain. I wish these "landing pages" became a standard, or that a standard repository for them became available. Something like, this is our technique, these are the relevant papers, and here is some demo code.
