In which we see how an agent can take advantage of the structure of a problem to construct complex plans of action.


The task of coming up with a sequence of actions that will achieve a goal is called planning. We have seen two examples of planning agents so far: the search-based problem-solving agent of Chapter 3 and the logical planning agent of Chapter 10. This chapter is concerned primarily with scaling up to complex planning problems that defeat the approaches we have seen so far. Section 11.1 develops an expressive yet carefully constrained language for representing planning problems, including actions and states. The language is closely related to the propositional and first-order representations of actions in Chapters 7 and 10. Section 11.2 shows how forward and backward search algorithms can take advantage of this representation, primarily through accurate heuristics that can be derived automatically from the structure of the representation. (This is analogous to the way in which effective heuristics were constructed for constraint satisfaction problems in Chapter 5.) Sections 11.3 through 11.5 describe planning algorithms that go beyond forward and backward search, taking advantage of the representation of the problem. In particular, we explore approaches that are not constrained to consider only totally ordered sequences of actions. For this chapter, we consider only environments that are fully observable, deterministic, finite, static (change happens only when the agent acts), and discrete (in time, action, objects, and effects). These are called classical planning environments. In contrast, nonclassical planning is for partially observable or stochastic environments and involves a different set of algorithms and agent designs, outlined in Chapters 12 and 17.


Let us consider what can happen when an ordinary problem-solving agent using standard search algorithms—depth-first, A∗ ,...
