 The decision theories of Savage and Jeffrey, as well as those of their critics, apparently concern a single or “one shot only” decision; at issue is an agent’s preference ordering, and ultimately her choice of act, at a particular point in time. One may refer to this as a static decision problem. The question arises as to whether this framework is adequate for handling more complex scenarios, in particular those involving a series or sequence of decisions; these are referred to as sequential decision problems.
