Artificial Intelligence Beats us in Chess, not in Memory

The brain strategy for storing memories may lead to imperfect memories, but in turn, allows it to store more memories, and with less hassle than AI.

In the last decades, Artificial Intelligence has shown to be very good at achieving exceptional goals in several fields. Chess is one of them: in 1996, for the first time, the computer Deep Blue beat a human player, chess champion Garry Kasparov. A new piece of research shows now that the brain strategy for st
