And old belief of mine -if mine means something I am not sure- is that to recognize patters on any kind of situation you do not need to describe fully each situation from the beginning. I thinks kind of a modular method is used, at least by living organism. Suppose you play a tennis game and we freeze time in the moment your opponents is going to strike the ball with his racket and you must do sometyhing in order to prepare yourself. Well, clearly you does not try to "recognize" a full pattern in the sense you calcvulate the angle of th racket, the speed of the ball, the weather conditions, the states of the floor, the history of the gamne, the score so far, etc; you just make a first very simple appreciation respect of the general direction probably the ball will follow. Your righ or your left. With that you take some first measures. You run to left or rightside of the field. Then when the ball comes to you in the predicted corner you does not try to calculate everything respect to youir strike, but you just take a glance and try to see if the ball will come at high or low altitude. With that decided, your body takes some postures to answer. And then you maybe you begin to have a first, fuzzy idea respect to the corner you are going to respond. And so and so. In other words, in different phases you take just one decision and only the accumulated sum of all them makes the total pattern. The pattern is a result post factum, not ex ante. The same, I believe, could be done with chess programming. A simple example: the engine first see at very simple features of the board to decide if he must defend or attack. Decided that, another set of feastures in the table base let him decide if action is in queen or king side. And so and so. Finally you havve a patterns: You must atrtack in the king side and a sacrifice is advisable and searchable. then you unleash the full of your coe to look for the moves. Fernando
