It's basically proven that no good algorithms exist. At least that's what I took away. And almost everyone I've talked to. And many people online. I keep seeing "No you can't do it. It's NP-hard. Blah blah" discussions. The myth is pervasive but these problems are not intractable. At the time, my professor closed the final lecture with dramatic words (I'm paraphrasing slightly): And now you've learned that…
