🐌. Native speaker of American English. Linux user. Familiar with several programming languages in the procedural, OO, and functional paradigms.

Link rot is evil. Archive everything. The keyboard is king. Correctness over performance. Canonicalize, normalize, deduplicate. Don't repeat yourself. UTF-8 > UTF-16. Use static typing: good for tooling. Re-use; don't re-invent. Correctness, then clarity, then concision and elegance. Play devil's advocate. First understand opponents' positions.

comment Speeding up a numerical constrained quadratic optimization
@OleksandrR.: I tried NMaximize with Method->{"RandomSearch",Method->"QuasiNewton","PostProcess"->"KKT"} on a similar smaller problem (7 vars), but it fails after a long time with NMaximize::cvmit: "Failed to converge to the requested accuracy or precision within \[NoBreak]100\[NoBreak] iterations. ".

@OleksandrR.: What do you mean by using FindMinimum via the "RandomSearch" method of NMinimize?

@OleksandrR.: I thought FindMinimum only gives a local minimum.

There's a built-in CopyToClipboard function, but it doesn't seem to work, at least on Linux.
