While recent advances in offline reasoning techniques and online execution strategies have made planning under uncertainty more robust, the application of plans in partially-known environments is still a difficult and important topic. In this paper we present an approach for predicting new information about a partially-known initial state, represented as a multigraph utilizing Maximum-Margin Mu...

We consider a special case of partially observable Markov decision processes that arises when state information is perfect but arrives with a delay. We rst formulate the decision process in its standard form and derive the Bellman equation that corresponds to it. We then introduce a second decision process that has a much simpler Bellman equation than the rst, and is therefore, in general, much...

We extend the plan-recognition-as-planning technique to both explain the past and project the future. The Planning Projector helps users understand future possibilities in order to make better decisions.

Modern domain-independent heuristic planners evaluate their plans on the basis of their length only. However, in real-world problems there are other criteria that also play an important role, such as resource consumption, profit, safety, etc. This paper extends the GRT planner, an efficient domain-independent heuristic state-space planner, with the ability to consider multiple criteria. The heu...

Imagining the future helps anticipate and prepare for what is coming. This has great importance to many, if not all, human endeavors. In this paper, we develop the Planning Projector system prototype, which applies plan-recognition-asplanning technique to both explain the observations derived from analyzing relevant news and social media, and project a range of possible future state trajectorie...

Theory of mind (ToM) is required when reasoning about mental states such as knowledge, beliefs, desires, and intentions. Many complex reasoning tasks require domaingeneral cognitive resources such as planning, resistance to interference, and working memory. In this paper we present a study of the additional cognitive costs of reasoning about mental states. We presented participants with sequent...

strategic environmental assessment can be viewed as a process to integrate the concept ofsustainable development into planning. in this context, sea can be regarded as a method that regulates theplanning process to a state of sustainable development. however, to reach that goal it is necessary to achieve full integration of planning and the sea process.therefore this paper considers the integra...
