That brute force 1/0 algorithms make for a good game of chess, Deep Blue if not others has proven. That this makes them interlligent I for one and many a psychologist as well I imagine, would dispute. Intelligence is obviously more than simple boolean operations on data-bits, at least I hope so. When I play a game of chess, admittedly far worse than Deep Blue, I rely on some amount of reasoning, some memorized tactical/positional rules, and a certain amount of inspiration. The first to an extent computers have, the second they are masters of, and the third is completely beyond them. Certainly Deep Blue never claims to have anything like intelligence, it is marely a multi-processor, dedicated, beast of a machine. A super-calculator if you will. Neural Nets and analog computers come far closer from my understanding, to AI, but none has been developed which can come close to Kasparov in chess. I don't know if I'm adding anything new to the discussion here, but it seems to me that there are two fundamental points which need to be nailed down. First that it is possible for a task such as chess to be solvable in different ways human intelligence and computational brute force can both be perfectly qualified approaches, but their both being succesfull does not make them equal nor even necessarily similar. Second that not all computers approach problem solving in the same way, some use brute force, point systems memory and far-sightedness, some use "learning" algorithms and neural nets, some use both. But it is important to note that the one which has beyond any doubt lent superiority to the computer over the average or indeed any human is the first attribute, brute force. This is not intelligence, and nobody says it is. Using the word intelligence in it's defenition therefore, is a mistake. Which is not to say that computers don't play a damn good game of chess. ---pedro
