In the African dry season (when food is more readily available as the pools shrink), it builds a tree nest in which two or three eggs are laid. It is known to be
A New Kind of Science of traffic, material fracture, crystal growth, biological growth, and various sociological, geological, and ecological phenomena. Another feature of simple programs is that, according to the book, making them more complicated seems to have little effect on their overall complexity. "A New Kind of Science" argues that this is evidence that simple programs are enough to capture the essence of almost any complex system. In order to study simple rules and their often complex behaviour, Wolfram argues that it is necessary to systematically explore all of these computational systems and document what they do. He further argues that this study should
