TALplanner in IPC-2002: Extensions and Control Rules
TALplanner is a forward-chaining planner that relies on domain knowledge in
the shape of temporal logic formulas in order to prune irrelevant parts of the
search space. TALplanner recently participated in the third International
Planning Competition, which had a clear emphasis on increasing the complexity
of the problem domains being used as benchmark tests and the expressivity
required to represent these domains in a planning system. Like many other
planners, TALplanner had support for some but not all aspects of this increase
in expressivity, and a number of changes to the planner were required. After a
short introduction to TALplanner, this article describes some of the changes
that were made before and during the competition. We also describe the process
of introducing suitable domain knowledge for several of the competition
domains
Classical quasi-trigonometric matrices of Cremmer-Gervais type and their quantization
We propose a method of quantization of certain Lie bialgebra structures on
the polynomial Lie algebras related to quasi-trigonometric solutions of the
classical Yang-Baxter equation. The method is based on so-called affinization
of certain seaweed algebras and their quantum analogues.Comment: 9 pages, LaTe
WHO ARE RESOURCE NONUSERS AND WHAT CAN THEY TELL US ABOUT NONUSE VALUES? AN APPLICATION TO COASTAL WETLAND RESTORATION
This paper assesses the potential for incomplete definitions of resource use to influence estimates of nonuser WTP, and whether uses underlying certain use values may escape measurement using standard mechanisms applied to distinguish resource users from nonusers. Empirical results are drawn from a stated preference analysis involving coastal wetland restoration.Resource /Energy Economics and Policy,
TRANSFJO. Hydrophysical observations in the Frierfjord, the Drammensfjord and the Iddefjord July-December 1997. Data report
The strategic institute programme, TRANSFJO, relies heavily on a fjord model developed at NIVA. To validate and further develop the physical part of the model, extensive measurements of the basic hydrophysical and meteorological parameters in the Frierfjord, the Drammensfjord and the Iddefjord were carried out in July-December 1997. This opportunity was also used to check out instruments and methods to be used in later stages of the program. In technical terms the field studies were a success. With few exceptions the instruments functioned properly, and the malfunctions should be eliminated through better pre-use checking and better deployment procedures. The general impression is that the field studies have produced the kind of data sets which are needed for further development of the model. Furthermore, the data seem to contain new knowledge of hydrophysical processes in fjords in southern Norway. This element will be looked into in 1999
Herding cats: observing live coding in the wild
After a momentous decade of live coding activities, this paper seeks to explore the practice with the aim of situating it in the history of contemporary arts and music. The article introduces several key points of investigation in live coding research and discusses some examples of how live coding practitioners engage with these points in their system design and performances. In the light of the extremely diverse manifestations of live coding activities, the problem of defining the practice is discussed, and the question raised whether live coding will actually be necessary as an independent category
