algorithms - trust the process

An algorithm is a formal process that will produce the same results every time it is run.

examples: solving a multiplication problem; tic-tac-toe; a computer program; a cooking recipe

1 - substrate neutrality - by hand or by machine, it still works

2 - underlying mindlessness - zeros and ones; lots of meaningless small decisions adding up to something that is judgemental or wise

3 - guaranteed results

emergent dynamics

The process of unpredictable, complex pattern formation from simpler rules.

The emergence of a system's global properties and capabilities which are not prespecified by network design and are difficult or impossible to predict from knowledge of its constituent parts

What is the Game of Life?
by Paul Callahan

The Game of Life (or simply Life) is not a game in the conventional sense. There are no players, and no winning or losing. Once the "pieces" are placed in the starting position, the rules determine everything that happens later. Nevertheless, Life is full of surprises! In most cases, it is impossible to look at a starting position (or pattern) and see what will happen in the future. The only way to find out is to follow the rules of the game.

New book proposes 'A New Kind of Science'  (no longer available for free)
by Matt Crenson
Associated Press, June 9, 2002

"A New Kind of Science" proposes that simple rules, not complex equations, are the key to such profound scientific mysteries as the structure of the universe and the incredible diversity of life on Earth. ...

"A New Kind of Science" is rooted in Wolfram's discovery during the 1980s that very simple computer programs known as cellular automata can produce strikingly complex results. In their most basic form, these programs take a pattern of gridded black and white squares and add to or modify them according to simple rules. Such programs usually generate beautiful checkered, striped and nested patterns that can exhibit incredible intricacy.

But Wolfram's obsession is the occasional cellular automaton that reels off a random pattern of black and white squares ad infinitum.

You can make one of these curiosities by filling in some of the squares in the top row of a sheet of graph paper. Then move to the next row of squares. Blacken a square unless the one directly above it and both of its neighbors are the same color, or the one above has a black neighbor on the left and a white neighbor on the right. Then go to row three, repeat the process, and so on.

Wolfram has programmed computers to do this simple exercise and similar ones millions and millions of times over.

"What I found - to my great surprise - was that . . . even some of the very simplest programs that I looked at had behavior that was as complex as anything I had ever seen," he wrote.

No amount of careful observation, no mathematical equation could ever predict what the next row of squares produced by one of these simple programs will look like. The only way to find out is to follow the rule.

Why would a software millionaire with impeccable scientific credentials spend years poring over such apparent trivialities?

Well, Wolfram explains, when traditional science encounters something with no mathematically reducible pattern, it simply throws up its hands. But his experiments show that apparently random processes can arise from surprisingly simple rules.

"It's our intuition that when we see something in nature that looks complicated, then somehow the explanation must be complicated," Wolfram said. "The surprising thing that I've found is that in the world of simple programs, this is not the case."

His book argues that nature doesn't require complicated explanations either. If he's right, scientists should be able to expose some fairly simple machinery buried deep inside some of nature's most seemingly complex creations.

"What I'm trying to do here is answer some of the questions that traditional science hasn't had much success in answering," he said.

Seeing Around Corners (no longer available for free)

Atlantic Monthly, April 2002

The new science of artificial societies suggests that real ones are both more predictable and more surprising than we thought. Growing long-vanished civilizations and modern-day genocides on computers will probably never enable us to foresee the future in detail—but we might learn to anticipate the kinds of events that lie ahead, and where to look for interventions that might work.
