Next Generation CPU Refrigerators
Iddo Genuth writes "Researchers at Purdue University are developing a miniature refrigeration system, small enough to fit inside laptop computers. According to the researchers, the implementation of miniature refrigeration systems in computers can dramatically increase the amount of heat removed from the microchips, therefore boosting performance while simultaneously shrinking the size of computers."
Say pieces on a board, make each a pair with another piece.
like...
|55|33|66|
|44|66|55|
|33|44|22|
|22|11|11|
so figure out how a piece can move.
pick any piece, try to move it somewhere.
when you move a piece you have to move it's pair at the same time.
when you move to a piece it's pair has to move at the same time too.
a piece always becomes a pair with the piece it moves to.
no matter how many pairs, there's only one answer to how a piece can move.
A common problem type, I forget what it's called.
There's only one answer for how any piece can move.
A piece always goes where a piece leaves.
You can't move a piece that moves where the piece came from.
No such thing as a free space, a piece always moves to another piece.
A pair never moves to a pair.
A piece works out to move where another piece can get back to where a piece moves from.
so try this...
draw starting at each piece a line that shows the piece it moves to, and each piece to move for how a piece moves back
where it starts.
see this as a machine diagram.
move a piece then figure the machine diagram again, it's the same machine though...
see how every other piece moves another way now?
what happened for how the machine moved?
Bart! Go to your room!
+1 funny too bad i dont have any mod points ;(
