Taxpayer support for public colleges has been falling sharply in recent years, not only in New York but around the country, and this has lately been causing a great deal of concern among many administra t o r s. The trend has also led to j o l t i n g , unpredictable tuition i n c r e a s e s. But CUNY has developed a long-term plan that could become a national model for the funding of public c...

A key issue in interactive storytelling is how to generate stories which are, at the same time, interesting and coherent. On the one hand, it is desirable to provide means for the user to intervene in the story. But, on the other hand, it is necessary to guarantee that user intervention will not introduce events that violate the rules of the intended genre. This paper describes the usage of a p...

The ability of a planner to modify a plan is considered as a valuable tool for improving ee-ciency of planning by avoiding the repetition of the same planning eeort. From a computational complexity point of view, however, it is by no means obvious that modifying a plan is computationally as easy as planning from scratch if the modiication has to follow the principle of \conservatism," i.e., to ...

This paper addresses the indexing and retrieval issues in the context of the case-based plan recognition. The indexing and storage mechanisms utilize the knowledge about planning situations that enable the recognizer to focus its search to a subset of the plan library containing relevant past plans. A two-level abstract indexing scheme, along with the incremental construction of the plan librar...

We present the PHATT algorithm for plan recognition. Unlike previous approaches to plan recognition, PHATT is based on a model of plan execution. We show that this clarifies several difficult issues in plan recognition including the execution of multiple interleaved root goals, partially ordered plans, and failing to observe actions. We present the PHATT algorithm’s theoretical basis, and an im...

ion and Indexing Although the intermediate states are very helpful when recognizing plans with incomplete plan libraries, the statespace for a given planning domain may be quite large (Kerkez and Cox, 2001). A large number of possible situations negatively affect the retrieval efficiency of the recognizer. We developed an indexing and retrieval scheme based on the concept of state abstraction t...

introduction: breast conserving radiotherapy is one of the most common procedures performed in any radiation oncology department. a tangential parallel-opposed pair is usually used for this purpose. this technique is performed using 2d or 3d treatment planning systems. the aim of this study was to compare 2d treatment planning with 3d treatment planning in tangential irradiation in breast conse...

The ability of a planner to reuse parts of old plans is hypothesized to be a valuable tool for improving eeciency of planning by avoiding the repetition of the same planning eeort. We test this hypothesis from an analytical and empirical point of view. A comparative worst-case complexity analysis of generation and reuse under diierent assumptions reveals that it is not possible to achieve a pro...
