Supposedly HN likes only really highly relevant comments and viciously down votes anything else, especially jokes, and everything else, no matter how serious or relevant, by the user they are down voting. Here I've been viciously, bitterly, attacked by some people apparently totally pissed off at me for next to nothing, a simple contribution follow up, a famous quote from the movie Casablanca, as a follow up to a post with the earlier part of that famous quote from Casablanca. So, my post on Lagrangian relaxation, that took much of an afternoon to write, and with careful theorems and proofs, with some material not so easy to find, especially in such a succinct, careful, and complete form, and that stands to be of high interest to anyone interested in simulated annealing, gets downvoted -- a joke about my post does not, and my response to the joke post does. HN is getting to be a very nasty place, not nearly as nice as, say, Reddit. Sorry HN. Sam, PG, you've got a problem. You need to look at your log files and find who has decided to hate me and down vote anything I post, no matter what I write. My post on Lagrangian relaxation is right up there in quality with some of the best expository writing in optimization, and I know enough to know. That I get down voted is the problem of HN, not my post. In the past few days, the bitter, hostile, personal attacks on me have cost me 70+ points, no doubt to the great pleasure of my attackers. I'm being bitterly attacked personally, for no good reason, and now independent of what I post.
