Ariadne's boyfriend/son/??? had to go into a labyrinth for some reason and then find his way back out.

Boyfriend Theseus was in the maze after killing the Minotaur. She fled with him when he returned to Athens, but he dumped her on Naxos, where they sold cheap CDs. "There she found solace for her abandonment in the love of Dionysus" (presumably in his four-poster).

(The above is (in part) a paraphrase from Dictionary of Mythology).

Let's not confuse things here Smile (Greek mythology is confusing enough without additional inventions)

Ariadne's thread was used to get back out of the labyrinth.
During that phase there was neither trial nor error nor backtracking of any kind (that may have happened earlier, but...)
We are never told exactly HOW Theseus found the Minotaur (holler "hey stupid Mino, here I am, come and get me!!!"? who knows?

So I'd say "Ariadne's Thread" is a bad pick in terms of "historical" accuracy, but a perfect name for a method, since everyone seems to be able to immediately figure out the method from the name.

I wish more user's manuals were like this: immediately obvious (and less technically "correct")

BTW, can anyone give a similar colorful explanation for Bowman's Bingo? I picture something like a deer hunt where the hunters are blindfolded and the deer yells "Bingo!" when somebody actually manages to hit it by pure chance. (now we can calculate the respective probabilities of a deer yelling "Bingo" and a chance hit, but I'll leave that to the more serious-minded Wink )

bowman bingo, everyone knows how to play bingo???
http://www.setbb.com/phpbb/viewtopic.php?t=52&highlight=bowman+bingo&mforum=sudoku

not sure if that link does anything for you, but bowman bingo works by covering cells with chips much like in a game of bingo. its a manual search for contradiction chains. and what I gather from the discussion is that the originator of the manual process was Bowman.

now something colorful?? imagine playing bingo with arrows??? just aim and shoot. that is how you would start a bowman bingo search.

WOW!!!

Shocked Shocked


Thanks, Norm! I'm impressed. There's actually a method behind the catchphrase ...

Too bad ... Evil or Very Mad

I was thinking more along these lines (with deer, of course)

Ariadne's thread is, as I understand it, a guess: Choose A, not B. Follow the implications of A. If the choice of A results in a contradiction, follow the thread backwards, and choose B.

Bowman's Bingo is programmed in Sudoku Susser. I have not found it useful for explaining possible pencil and paper solving techniques.

Look for <3> in Row 9. Then, look in Row 1, and then in Row 9.
