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 ...

Planning by Rewriting (PbR) is a new paradigm for efcient high-quality planning that exploits plan rewriting rules and e cient local search techniques to transform an easy-to-generate, but possibly suboptimal, initial plan into a high-quality plan. Despite the advantages of PbR in terms of scalability, plan quality, and anytime behavior, PbR requires the user to de ne a set of domain-speci c pl...

One kind of temporal reasoning is temporal projection-the computation of the consequences of a set of events. This problem is related to a number of other temporal reasoning tasks such as story understanding, planning, and plan validation. We show that one particular simple case of temporal projection on partially ordered events turns out to be harder than previously conjectured. However, given...

We present the application of the Planning by Rewriting (PbR) framework to query planning in distributed and heterogeneous environments. PbR is a new paradigm for e cient high-quality planning that exploits plan rewriting rules and e cient local search techniques to transform an easy-to-generate, but possibly suboptimal, initial plan into a high-quality plan. The resulting planner is scalable, ...

Being a nurse today and striving for 100% job satisfaction while ensuring a patient's well-being is not an easy task in the current changing and challenging environment. However, careful planning might be the key to success. This article focuses on 'How to Plan' and gives some practical tips for nurses in their daily work. The article then offers three case stories of renal units that have deve...

A concise outline of background is given on assistive methods for writing and communicating for non-speaking people, highlighting the role of efficient text entry in augmentative and alternative communication (AAC). AAC systems are designed to assist people with communication impairments to interact with others and to compose messages and other documents. Efficient text entry is therefore of gr...
