Mathematics - 30 June 2007

Please don't tell that it is how integers are distributed, or that is definition of integers and so on. I found this problem in a book, and so please try to provide some proof based on number theory. I have some basic number theory background.

How do I prove that this algorithm can solve all n x n mazes?

The entrance of the maze is at the bottom left and the centre are the middle 4 squares. The algorithm is to first set an arbitary direction as North (in this case we set North as North), then moving in that direction until an obstacle is met. If there is an obstacle at North, move East. If there is an obstacle at East, move South. If there is an obstacle at South, move West. Keep repeating these steps. Eventually we can reach the centre of the maze. The robot (or person) is also clever enough not to retake the route taken previously if it has returned to the starting point, as in it will ignore the first opening to another route (as it had taken this route in the first try). If it returns to the starting again, it will ignore the first and second routes and repeat the whole process again. How do I prove or if possible improve this algorithm? Much help appreciated, thanks.

Three, Five, Seven is a two player game. To win you have to make your opponent take the last match. You can take any number of matches from 1 row only. You must take at least one match each turn. The game is set up as shown below.

I I I <-- row 1
I I I I I <-- row 2
I I I I I I I <-- row 3

My task is to devise a statagy to win the game. I need help if anyone can. Best answer goes to the one that was the most help within 4 days thnx.

Sometimes, one rule of arithmetic can be replaced with another one, and save time for both writer and reader. For example:

A + A + A + A + A... ["A" repeated A times] = A x A

A x A x A x A x A... ["A" repeated A times] = A ^ A

Now my question is:

A ^ A ^ A ^ A ^ A... ["A" repeated A times] = A [what goes here?] A

And whatever goes there, what do you write when that way of writing too is similarly exhausted, and what do you write when that too is exhausted, and so on, and so on?
