Run python life_gui.py [pattern-file] to start a simulation. One way to reach from a point (x1, y1) to (x2, y2) is to move abs (x2-x1) steps in the horizontal direction and abs (y2-y1) steps in the vertical direction, but this is not the shortest path to reach (x2, y2). The universe of the Game of Life is an infinite, two-dimensional orthogonal grid of square cells, each of which is in one of two possible states, live or dead (or populated and unpopulated, respectively). Here, the position of a data item is accessed by using two indices. Delaying the calculation (or creation) of each item in an infinite data structure until it is needed eliminates the problem of having to create an infinite data set. , and , to cite but three.
