My question is whether Mr. >Kaufman is correct in his assumption that Selective search is superior to Brute >Force search? Also, if I remember correctly, Novag claimed according to Mr. >Kaufman that Selective "On" was superior. Is there an answer from some authority >as to whether Selective or Brute Force results in a higher rating? Hi: I am not authority in this but just an old fart that has had too many computers along too many time and read too many about this to suspect with some ground that brute or selective approaches has his strenghts and his weakneses, but in the long run a good selective approach seems to be better as much is capable of deeper searches and so can avoid traps, positional mistakes etc in better way that the brute force. There are another reasons long to explain and beside I am not the man to do so. This one, the brute force appraoch, is incarcerated inside a narrow horizon due to the time it expends analyzing all in each branch of the tree, but then this very same fact let the program to be more eficient in tactical shots inside his narrowed horizon. Nevertheless, as selective approach is not suicidical, rarely they commit mistakes that entails a fast defeat, but on the contrary a brute force approach is prone to commit any mistake possible beyond his horizon. So, selective seems to be superior and facts show it is so. Demise of Spracklen team was due, people said, to his unbreakable attachment to brute force or better said to a variation of it called full width search. I hope I am not too much mistaken in all this Greetings from Chile fernando Fernando
