In this paper, we show that, amongst n uniformly distributed unit balls in R , the expected number of maximal non-occluded line segments tangent to four balls is linear, considerably improving the previously known upper bound. Using our techniques we show a linear bound on the expected size of the visibility complex, a data structure encoding the visibility information of a scene, providing evi...

In this paper we report on initial research we have conducted on a computational theory of prose style. Our theory speaks to the following major points: 1. Where in the generation process style is taken into account. 2. How a particular prose style is represented; what "stylistic rules" look like; 3. What modifications to a generation algor i thm are needed; what the deci~'on is that evaluates ...
