Yeah, I have fair point. I do all of my journal writing in Quarto, so that I can swap between formats, which lets me write Quarto => Typst. If a journal requires LaTeX, you just swap the engine and Quarto produces the LaTeX file.

The journals that I normally submit to will often accept pdf files for the review process, but want .tex source files once the paper is accepted 🫠 Have you dealt with that before?

This story of the discovery of Alison Doig the person is wild

The first author of that paper was his own supervisor, Ailsa Land, who was still at the London School of Economics. But he did not know what had become of the second author. “All I know is that she was Australian and that she shares your name,” Gilbert said to me.

Many years later, I started teaching optimisation (and her own branch-and-bound method) at the University of Melbourne. I always mentioned the mystery of this Australian woman who was my namesake and who had disappeared after publishing such an influential paper.

After one of these classes, a student approached me and said, “Professor, there’s a tutor here named Alison. Maybe it’s her.”

With little hope, I looked into it, and to my surprise, the tutor was indeed Alison Doig, now Alison Harcourt. My desire was to run, knock on each one of my colleagues’ doors and ask: “Do you know who that woman is?”.

Important to note their local search neighborhood. It is not just adding a single vertex (if so, the problem for independent sets is easy—build two maximal ind sets, one from each endpoint of an edge). Rather, it is about dropping one vertex and adding two others

“We show that computing two locally optimal solutions is NP-hard for various natural unweighted local search problems, including Maximum Independent Set, Minimum Dominating Set, Max SAT, and Max Cut.”
