Time, chance and action

چکیده
To operate intelligently in the world, an agent must reason about the consequences of its ac tions. The consequences of an action are a func tion of both the state of the world and of the action itself. In realistic domains we cannot ex pect to have complete information, so a repre sentation for reasoning about actions must be able to express uncertainty concerning the state of the world and the effects of actions and other events. This paper presents a future-branching temporal probability logic for reasoning about actions. The logic can represent the probabil ity that facts hold and events occur at various times. It can represent the probability that actions and other events affect the future. It can represent concurrent actions and conditions that hold or change during execution of an ac tion. The model of probability relates proba bilities over time. The logical language inte grates both modal and probabilistic constructs and can thus represent and distinguish between possibility, probability, and truth. Several ex amples illustrating the use of the logic are given.

Artificial Intelligence , 4 logic of time , chance , and action for representing plans
This paper integrates logical and probabilistic approaches to the representation of planning problems by developing a first-order logic of time, chance, and action. We start by making explicit and precise commonsense notions about time, chance, and action central to the planning problem. We then develop a logic, the semantics of which incorporates these intuitive properties. The logical languag...
متن کاملA chance-constrained multi-objective model for final assembly scheduling in ATO systems with uncertain sub-assembly availability
A chance-constraint multi-objective model under uncertainty in the availability of subassemblies is proposed for scheduling in ATO systems. The on-time delivery of customer orders as well as reducing the company's cost is crucial; therefore, a three-objective model is proposed including the minimization of1) overtime, idletime, change-over, and setup costs, 2) total dispersion of items’ deliver...
متن کاملAction Change Detection in Video Based on HOG
Background and Objectives: Action recognition, as the processes of labeling an unknown action of a query video, is a challenging problem, due to the event complexity, variations in imaging conditions, and intra- and inter-individual action-variability. A number of solutions proposed to solve action recognition problem. Many of these frameworks suppose that each video sequence includes only one ...

Let us start with an example of health policy analysis in action. Within that category of countries loosely known as ‘the West’, quite basic differences exist in attitudes to health policy and also actual health policy. Comparing the US with mainland Europe and indeed Canada, for example, one perceives a difference in attitude on the part of the majority towards collectivism and individualism i...
