Evolution of Chess Playing Machines
In his book, Mind Master , Viswanathan Anand talks about the evolution of chess playing machines. “In the beginning the (chess) engines were ridiculously weak… The way they approached a problem was to consider every possible move to counter it, but because they were not looking far enough they would sometimes offer the most ludicrous solutions.” Since computers did brute force calculations of every possible move, they could calculate only X number of moves. Yes, that number X would keep increasing, but that just moved the limit. Such a limit would sometimes led to weird situations: “For a long time… the machines would go wrong at a point where a long-term decision came into play.” While computer couldn’t calculate that far out, humans could intuitively feel it. But even with that constraint, over time, humans began to find it increasingly difficult to beat computers. Why? “Even when we’d outplayed engines for long stretches in a game, we’d end up making a ...
