  2. Yep, I agree. Once I got about 80% through, I was stuck finding a logical answer to the end (albeit it was staring right at me), I had two alternatives to choose from and found one that worked. I was very unhappy with that way out b/c there had to be a logical step-by-step solution and a few minutes later found it (it was that beer/bluemaster had to go to the 5th house and then everything else followed.)
    Nice puzzle though.

  3. i have a bone to pick with einstein as well ...

    he said the ..."The green house is at the left side of the white one."


    BUT he didn't say immediately positioned at the left side. this might mean a few houses away at the left. i had to make the assumption that what he really meant was RIGHT TO THE LEFT.

    this assumption added 42 secs to my time:mad:

  4. hold your horses. i did the same thing anyone else would do with a pencil and a piece of paper. just because i used excel does not mean i did not use logic and just moved things around til they fit. i could explain step by step how i solved it.

  5. He's just pulling your chain.

    I used a matrix, like other people mentioned, and
    little logic nodes connected with arrows to show the relationships
    to logically solve it. ( Years ago when I first saw it ).

    No brute force is required with a matrix approach.

    Although I kinda cheated on the last step... I had
    two possibilities left without a clue to which was the
    correct one, so I just plugged both in to see which worked.
    End of problem. Im sure there was a logical clue somehere,
    but SOMETIMES brute force is the most efficient method. :D

    Deep Blue beat Kasparov using brute fruce, after years and
    years of people working on complex algorithms to beat him.
    Guess they finally gave up, and decided a few thousand
    processors would do the job just fine :D

    peace

    Believe it or not, I have asked the above during interviews.

  7. You don't need to make the assumption that the green house is next to the white one. It follows from the original clues.

  8. I suspected it might be "college math" level in the US. Where I come from, it would only be considered non-trivial in high school. Or maybe some of the fields in which you can get a degree without ever progressing past high-school level thinking (like literature or history).

  9. yes you are right ... but only about half way into the solution, but at the outset this is not apparent and had to be assumed.


    One, what's the answer to yours?

  10. Yes, since you come from that great super-smart erudite sub-section of the upper-cream of our society.
