Re: Where is behavior AI now?

I'm not quite sure what you meant by this last comment, but an obvious
case where a simple state-machine breaks down and doesn't handle
short-term history [memory] well is the repetitive collision loops that
Tim.P mentioned.

OTOH, have you ever seen a bump-and-go toy get stuck in a corner?

Is the real issue large enough memory to record a history, or limited
programming in ways to render the problem moot in the first place.

Though not necessarily as efficient in all cases, using a random
solution to getting out of a corner may be just as effective as going
through a known sequence, the latter of which would imply storing a
history of the failed attempts.

Even Tim's solution, which I find elegant in its simplicity, doesn't
need a history to work. Panic is an excellent behavior. In us it might
rise from some chemical excreted each time we try something that doesn't
get us out of a jam. We don't actually need to keep a history of what
we've tried and what we haven't. At some level, we go into panic mode,
becoming in effect a bump-and-go toy. At that level, we're not thinking
rationally, and histories be damned. Funny thing is that this behavior
is endemic to us and most living creatures.

If we're really going to get into behaviorism, we need to look at the
random factor and include irrational thought processes. What I find
lacking in most trials of behavior-based AI and robotics is that the
behavior is too Spock-like. What we might term "negative" behaviors can
be powerful problem solvers, and there are billions of examples of these
negative behaviors in biology.
