Quote of the day

"One important detail is that actions that have not yet been tried in a state s are always assumed to lead immediately to the goal with the least possible cost, namely h(s). This optimism under uncertainty encourages the agent to explore new, possibly promising paths.

- Artificial Intelligence: A Modern Approach (Russell&Norwig)

Amusing how theory can guide one's life as well as explain the inevitable disappointments. Of course, Mae West anticipated theory with "Whenever I have to choose between two evils, I always like to try the one I haven't tried before"

Makes sense. If you know the outcome of one action is unfavorable, but are unsure of the outcome of the other option, might as well roll the dice and see what happens. And, hopefully, you'll live to tell about it.

Hopefully.

Not living to tell about it violates the condition of "safely explorable" that search strategies usually depend upon. But so does life.
