Our main contribution is a rather general lemma that can be used to obtain upper bounds on the expected number of extreme points for a large class of noise distributions. We then apply this lemma to obtain explicit bounds for random noise coming from the Gaussian normal distribution of variance σ² and the uniform distribution in a hypercube of side length &epsilon. For these noise distributions we show upper bounds of O( (1/ σ )^d * log^3/2 * d - 1 n ) and O( ( (n log n) / ε )^d/(d+1) ), respectively. Besides its theoretical motivation our model is also motivated by the observation that in many applications of convex hull algorithms the input data is inherently noisy, e.g. when the data comes from physical measurement or imprecise arithmetic is used.}, author = {Damerow, Valentina and Sohler, Christian}, booktitle = {Proceedings of the 12th European Symposium on Algorithms (ESA'04)}, isbn = {9783540230250}, issn = {0302-9743}, title = {{Extreme Points Under Random Noise}}, doi = {10.1007/978-3-540-30140-0_25}, year = {2004}, } @inproceedings{18785, abstract = {A limiting factor in the performance of a render- ing system is the number of state changes, i.e., changes of the attributes material, texture, shader program, etc., in the stream of rendered primitives. We propose to include a small buffer between appli- cation and graphics hardware in the rendering sys- tem. This pipeline buffer is used to rearrange the incoming sequence of primitives on-line and locally in such a way that the number of state changes is minimized. This method is generic; it can be easily integrated into existing rendering systems. In our experiments a pipeline buffer reduces the number of state changes by an order of magnitude and achieves almost the same rendering time as an optimal, i.e., presorted, sequence without pipeline buffer. Due to its simple structure and its low mem- ory requirements this method can easily be imple- mented in software or even hardware.}, author = {Sohler, Christian and Krokowski, Jens and Räcke, Harald and Westermann, Matthias}, booktitle = {Proceedings of the Vision, Modeling, and Visualization Conference (VMV 2004)}, title = {{Reducing State Changes with a Pipeline Buffer}}, year = {2004}, } @misc{18797, author = {Peckhaus, Volker}, booktitle = {Mathematical Reviews [MR 2004a:03010; online: MathSciNet 1 971 366]}, title = {{Murawski, Roman, “Truth vs. Provability - Philosophical and Historical Remarks”, Logic Log.
