 Fruitless Recursion as a Strategy

Luring an opponent into fruitless recursion can be an effective strategy in other games, too. One of the most colorful, bizarre, and fascinating episodes in the history of man-vs.-machine chess came in a 2008 blitz showdown between American grandmaster Hikaru Nakamura and leading computer chess program Rybka. In a game where each side got just three minutes on the clock to play all of their moves or automatically lose, the advantage surely seemed to be on the side of the computer—capable of...

 Students Reliant on Computer Simulations Lack the Technic...

In the 1980s, alternate visions of computers and the future of design were expressed in competing views about programming. Some architects believed that designers needed to learn advanced programming. If designers did not understand how their tools were constructed, they would not only be dependent on computer experts but less likely to challenge screen realities. Other architects disagreed. They argued that, in the future, creativity would not depend on understanding one’s tools but on usi...

 Where's Transparency With So Many Layers of Abstraction?

Some older scientists, for example, justify their use of opaque software by pointing to the infinite regress of computer representations. After all, they argue, it doesn’t really mean much to know how your simulation is programmed if all you are looking at is a high- level computer language. The “real guts” of the program is in assembly language and in all that lies beneath that, and no one wants to go to that level with today’s complex machines. In the 1980s, Professor Barry Nilo= in...

 Loss of Legacy Programmers Means Loss of Systems Understa...

At Livermore, a legendary senior weapons designer is about to retire. At the Spring 2005 MIT workshop, his colleagues discuss this retirement and refer to it as “a blow.” They are anxious about more than the loss of one man’s ability to make individual scientific contributions. He has irreplaceable knowledge about the programming that supports current practice.10 His colleagues fret: “He has such a great memory that he hasn’t written down lots of important stuff. How will people kno...

The newer users only know the interface, the abstraction, they don't know the code beneath it.

 Don't Let the Simulation's Beauty Convince You It's Real

The architecture faculty who designed Project Athena’s Garden dreamed of transparent understanding of design process; today scientists are reconciled to opacity and seeing only a CAVE’s shadows. Over the past twenty years, simulation has introduced its dazzling environments and we have been witness to our own seduction. A mechanical engineer instructs his students: “Don’t be fooled by the graphics.”17 Luft says that beautiful codes promote the “illusion of doing really great scien...

 Computing is Pop Culture without History

Binstock: You seem fastidious about always giving people credit for their work. Kay: Well, I'm an old-fashioned guy. And I also happen to believe in history. The lack of interest, the disdain for history is what makes computing not-quite-a-field. Binstock: You once referred to computing as pop culture. Kay: It is. Complete pop culture. I'm not against pop culture. Developed music, for instance, needs a pop culture. There's a tendency to over-develop. Brahms and Dvorak needed gypsy music ba...

 A Quantum Game

Bell came up with “nonlocal” games, which require players to be at a distance from each other with no way to communicate. Each player answers a question. The players win or lose based on the compatibility of their answers. One such game is the magic square game. There are two players, Alice and Bob, each with a 3-by-3 grid. A referee tells Alice to fill out one particular row in the grid — say the second row — by putting either a 1 or a 0 in each box, such that the sum of the number...

 Asimov Story on Computation

■ N 1958, American science fiction legend Isaac Asimov wrote a very short story called "The Feeling of Power." In it, lowly technician MyI ron Aub discovers that he is capable of duplicating the work of his computer by multiplying two numbers together on a piece of paper. Amazing! This miraculous discovery makes its way up the chain of command, where the generals and politicians are stunned by Aub's black magic. The top general is intrigued by the possibility that human calculations could g...

 Tablebases

t. In 1977, Thompson showed up at the World Computer Chess Championship th a new creation, a database that played the king and queen versus king and rook endgame perfectly. (KQKR is the abbreviation.) It wasn'1 an engine; there was no thinking required. Thompson had generated a database that essentially solved chess backwards, what we call retrograde analysis. It started from checkmate and worked its way back until it contained every single possible position with that material balance. Then i...

 Asymmetrical Psychology: Computers Use Knights Better Tha...

e. Chess players have the most trouble visualizing the moves of knights because their move is unlike anything else in the game, an L-shaped hop instead of a predictable straight line like the other pieces. Computers, of course, don't visualize anything at all, and so manage every piece with equal skill. I believe it was Bent Larsen, the first GM victim of a computer in tournament play, who stated that computers dropped a few hundred rating points if you eliminated their knights. This is an ex...
