Analyzing generalized planning under nondeterminism

چکیده
In automated planning, there has been a recent interest in solving class of problems, where single solution applies for multiple, possibly infinitely many, instances. This necessitates generalized notion plans, such as plans with loops. However, the correctness is non-trivial to define, making it difficult provide clear specification what we should be looking for. an influential paper, Levesque proposed formal analyzing plans. He motivated logical characterization within situation calculus that included binary sensing actions. argued from each state considered possible initially, plan terminate while satisfying goal. Increasingly, classical structures are being applied stochastic environments robotics applications. raises question look like, since Levesque's account makes assumption actions deterministic. this work, aim generalize handle nondeterministic outcomes, which may also accorded probabilities. By appealing extension probabilistic nondeterminism, will show definition, well goal achievability by Lin and Levesque, have limited appeal under nondeterminism. essence, they correspond one correct execution, unlikely adequate. Rather, propose delineate between satisfaction termination leading range criteria. To better study these criteria, position results broader context still allowing generality calculus, consider abstract framework loops, domains unbounded, and/or stochastic, continuous. Within framework, then prove numerous relationships including some impossibility categorically goals. Finally, notions more granular view than those discussed literature, strong planning cyclic planning.

Task decomposition on abstract states, for planning under nondeterminism
Although several approaches have been developed for planning in nondeterministic domains, solving large planning problems is still quite difficult. In this work, we present a new planning algorithm, called Yoyo, for solving planning problems in fully observable nondeterministic domains. Yoyo combines an HTN-based mechanism for constraining its search and a Binary Decision Diagram (BDD) represen...
متن کاملGeneralized Planning with Loops under Strong Fairness Constraints
We consider a generalized form of planning, possibly involving loops, that arises in nondeterministic domains when explicit strong fairness constraints are asserted over the planning domain. Such constraints allow us to specify the necessity of occurrence of selected effects of nondeterministic actions over domain’s runs. Also they are particularly meaningful from the technical point of view be...
متن کاملAnalyzing Generalized Tubes
Many objects in the real world are tubular in shape and this paper is about understanding this object class, which we refer to in the paper as generalized tubes (hereafter GTs). Intuitively, a GT is constructed by sweeping some planar closed curve (the GT cross-section) along a 3D space curve (the GT axis). First, we examine the GT class as a whole and identify two important GT subclasses where...
متن کاملRegular realizability problems and models of a generalized nondeterminism
Models of a generalized nondeterminism are defined by limitations on nondeterministic behavior of a computing device. A regular realizability problem is a problem of verifying existence of a special sort word in a regular language. These notions are closely connected. In this paper we consider regular realizability problems for languages consisting of all prefixes of an infinite word. These pro...
متن کاملOn Analyzing Planning Applications
It is hard to evaluate in current planning applications what aspects of the approach address each of the complexities of the problem. This results from the fact that the planning community is lacking a vocabulary to describe planning tasks and apphcations. This work is an effort towards descriptions of planning applications in terms that are useful 1) to extract conclusions from particular impl...
