Keith, here's aran's "starting hypothesis": 24r2c9=17r2c79
How is that the equivalent of r2c9<>24?
If starting a chain with a strong link is a "guess" then we might as well throw in the towel and give up the game. |

Well, aran him/herself said:

I believe that not 24 r2c9 is the equivalent of r2c9<>24
I still don't see it, but it doesn't matter. I asked if it was a guess, I did not characterize it as such.
In any event, I was trying to divine a reason to choose the starting point based on a uniqueness argument.
Best wishes,
Keith. |

Keith, from what I've seen, aran spends most of his time (in other forums) tackling extremely difficult puzzles. As such, he's accustomed to finding sub-patterns, like the 17 pair in r2c79, and seeing if he can take advantage of it. Since cell r2c9 is the only cell in the puzzle with four candidates, I can see aran homing in on it like that mosquito did to me yesterday evening.
Bottom Line: I seriously doubt if he "guessed".
Regards, Danny |

There are mosquitoes in Livermore?

Livermore is where I worked before retiring. It's over a 1,000 ft. "hill" from where I live -- Tracy. Most of the free-flowing water in CA goes through "The Delta" just a few miles north of here on its way to the San Francisco/Bay Area and out to the ocean. Unfortunately, way too many mosquitos are on this side of the hill. They spray the entire county most years from the air. |

That sounds like a bad idea. We encourage the bats.

Haha, that cracked me up.
Good local knowledge from a Detroit guy on his way to Great Britain. You must really get around! |

(In response to keith's post below : for some reason, the system won't seem to accept placing the quote first)
Putting an AIC into words inevitably obliges to resort to something along the lines of
- not a implies b
- if a is false then b is true
or using other symbols
~a=>b.
An AIC could - perhaps a lttle unfairly - be described as a guess which ends up as a truth.
After all, the starting point is based on something, and since the future truth remains to be established, what is that basis ? Guess, educated guess, hunch, intuition, promising looking position, interesting start, experiment, a touch of the unexpected...there are many contenders.
daj : thanks for the comment  I'll send you a mosquito net.

Side note to aran and others that encounter posting issues:
When the PHP software behaves squirrelly, checking the box "Disable HTML in this post" will often resolve the issue. |
