From that point, the action probabilities given state T j will sum to one, just as the action probabilities given state T k will sum to one, and there is no reason to expect that the most probable action from T j should be less probable than the most probable action from T k .
once an error occurs, search is of little help in recovering from it, since scores are based only on local decisions and not on any notion of state quality, and the error occurred precisely because an incorrect action was found to be more probable locally.
