Yes of couse. But you're looking very forward a lot I think. I follow that since a lot of time.
I have asked, personally, to Brent, Nocedal etc. in 2007, for using their code sources, https://metacpan.org/pod/PDL::Opt::NonLinear they were very moneyable at that time. They agreed. I agree with Linus Torvalds, AI, 95% of marketing. But I think you see to a lot forward. Fonts, is another matter, it is a real problem BTW, just this week because of a dist-upgrading I had to wait for an update. To small to read without glasses. An unknown reason. I think your idea Tim can be very good. But a lot of things in the numerical world need to be done/added. https://x.com/search?q=mcp&t=6s8XTuxpWGBbWodV53xBQA&s=09 - Greg Le ven. 20 juin 2025, 22:15, Grégory Vanuxem <g.vanu...@gmail.com> a écrit : > Hello Tim, *, > > Thanks for your response, but frankly speaking, I do not know how to > find your code.
