Should being the operative word. This refers to a "perfect" agent (emphasis added in text; thanks!).
People don't do this, as well they shouldn't, because we update poorly and need the original data to compensate.
If I remember the cards in play, I don't care about the discarded ones. If I don't, the discarded cards could help a bit, but that's not the heart of my problem.
What's a perfect agent? No one is infallible, except the Pope.
And even the Pope only claims to be infallible under certain carefully delineated conditions.
And as the tired old joke goes: bullet-proof glass.
This is a perfect agent, of theoretical interest if not practically realizable.
Assigning a probability to each possible world state?!? That is incredibly inefficient and wasteful. Any implementation attempt would result in slow stupidity - not anything intelligent.
