Hi everyone.. I have a new blog up for a couple of weeks-ish. It is mainly about my ideas on philosophy (some contains math related stuff), history, politics,...
So despite a death certificate being obtained, Yahoo were still not for turning? Doesn't surprise me, considering the problems I've had myself, although not...
The 'numbertheory' Yahoo group was very well-maintained, had a membership of 1200 and the discussion was of a high level of sophistication. Unfortunately the...
... Thanks - yes picking an odd number near the center or even at the exact center (if it's odd) would be the thing to do to get the game over with quickly...
Brilliant, sir. Of course, the disclaimer is that the optimal strategy doesn't guarantee victory, but it does increase your chances. And, if you have to choose...
The game described is one between two players - you and your opponent, for example. So yes, it is a scenario where, by definition, one player will win and one...
Peter's explanation for choosing a number on one of the extremes looks reasonable - normally after an incorrect guess there's some helpful information saying...
I am thinking that it is either you or your opponent who wins. Since any number is equally likely to occur, it doesn't matter which number you choose - your...
Hmmm... I like it. Even when I was wondering to myself that perhaps choosing from the extremities of the selection was the best way to go. I won't be attmpting...
Claim (I have a proof but maybe someone else wants to try to prove or disprove it): Say there are N numbers left, this is a generalization from those cases...
That's exactly the approach I was thinking of. When there are two numbers to choose from, it doesn't matter which number you choose; you have a 50-50 chance of...
Yes this looks like a more difficult and interesting problem - thanks Clooneman. I haven't solved it yet but consider that after the first player chooses, the...
The course numbering system is different at every college, so "Math 20" is meaningless outside of your college. Look up the course outline on the college web...
hi, I need to take a math 20 placement test at my home community collage, I took math back home in Lebanon and was instructed in French and therefore I am not...
I only quickly scanned through that site, but this looks slightly different than the well-known puzzle - this looks like there are three people, one who picks...
Yes, there is. It is well-known in computer science. See http://en.wikipedia.org/wiki/Binary_search_algorithm#Number_guessing_game -- Rick ... From:...
Here's one for you all to put your brains together about. A number is chosen between 1 and... say, 10, *inclusive*. Two players then take it in turns to guess...
Why is this guy targeting us? Does he think we have trouble attracting women? Most women light right up when I start talking about the differences between...
Please disregard my last post. I noticed a huge flaw when I got home. I'll re-post the problem using shift operator notation. A few definitions first....
Give a step by step proof that \sum_{i=0}^n (-a-b+1)^{n-i} *\binom{{n}{i}} *(a^i+b^i)\neq 1 for non zero integers a and b where n>2 Have a safe and happy...
