The court, enclosed by linen hangings, had the shape of two adjacent squares.
Each time he steps into one of four adjacent squares adjacent to the once he's in at the moment, and each time he chooses this next square randomly with equal probability.
On a 5-by-5-inch grid on a computer screen, the monkeys were shown a shape consisting of three adjacent squares, one blue and two red in various patterns.
The diffusion step is implemented as a type of random walk: Each molecule can move randomly to one of the eight adjacent squares if the square is empty.
The cavernous void beneath, conceived of as an extension of the adjacent square, will be planted with all the trappings of a public space: lawns, trees, cafes, benches and paved areas that will be "activated" by a programme of events.
First, we need to realise that a domino always covers two adjacent squares of the chessboard, which must always have the opposite colour.
The wave functions of two adjacent square QWs, (psi _{j}) and (psi_{j+1}), are approximated by those of free particles in two isolated wells separated by an infinitely thick barrier.
Since adjacent squares are of opposite colour, the remaining squares are not adjacent and hence cannot be covered by the last domino.
If the player steps on a square that contains a mine, the mine detonates and the player loses some health; if the square is mine-free, it is ''cleared" and displays the number of mines in the eight adjacent squares.
The first wavelet is the mean pixel intensity value of the whole image; the rest of the wavelets are computed as the difference in mean intensity values of horizontally, vertically, or diagonally adjacent squares.
