“I don’t know how to solve the problem, so I’ll just use the best method I know of for trying random solutions”

If your random guessing will provide a (previously unknown) solution, very well. But it probably won't.

I am not talking about "maybe it would", I talk about "it did, indeed".

I’m the world record holder at looking like myself

Everybody has few such records, but those are worthless. Some people however, solved a difficult puzzle. On this particular site I gave you a link, such a competition is going on. Maybe it reminds someone to the LW's PD agents competition?

Anyway, I don't hold any record there. An algorithm I designed and called it Pack'n'tile holds some. Follow the links, download the program and try it, if you want.

Sorry, I was unclear. By “best method I know for trying random solutions” I meant evolutionary algorithms. (Which I think of as “guess randomly, then mix guesses randomly, then mutate guesses randomly, then select randomly biased towards the the best you found, then repeat from step two”. Of course, there’s a bit of smartness needed when applying the randomness, but still.)

Some people however, solved a difficult puzzle.

I think we’re having mostly a terminology disagreement. I tend to think of EA as “finding a solution” rather than “solving the problem... (read more)

If it's worth saying, but not worth its own post (even in Discussion), then it goes here.

Given the discussion thread about these, let's try calling this a one-week thread, and see if anyone bothers starting one next Monday.
