Pinktoe : putting S trees on the web
Tree based methods in S or R are extremely useful and popular. For simple trees and memorable variables it is easy to predict the outcome for a new case using only a standard decision tree diagram. However, for large trees or trees where the variable description is complex the decision tree diagram is often not enough. This article describes pinktoe: a tool that converts S tree objects into web...
متن کاملInorder traversal of splay trees
Splay trees, a form of self-adjusting binary tree, were introduced by Sleator and Tarjan in the early 1980s. Their main use is to store ordered lists. The idea is to keep the trees reasonably well balanced through a ‘splay heuristic.’ Sleator and Tarjan showed that if amortised rather than worst-case times are considered, splay trees are optimal. Splay trees have the advantage of simplicity: th...
متن کاملAutomatic Generation of Hints for Symbolic Traversal
Recent work in avoiding the state explosion problem in hardware verification during breath-first symbolic traversal (BFST) based on Binary Decision Diagrams (BDDs) applies hints to constrain the transition relation of the circuit being verified [14]. Hints are expressed as constraints on the primary inputs and states of a circuit modeled as a finite transition system and can often be found with...
متن کاملStackless Ray Traversal for kD-Trees with Sparse Boxes
We present a new stackless ray traversal algorithm which makes use of kD-tree augmented with sparsely distributed bounding boxes. The proposed traversal algorithm is not restricted to start the hierarchy traversal at the root node and so it can exploit the knowledge of the ray origin. The algorithm achieves traversal times comparable with the traditional hierarchical traversal as well as recent...
متن کاملA Semi-Automatic Algorithm for Estimating Cobb Angle
Background: Scoliosis is the most common type of spinal deformity. A universal and standard method for evaluating scoliosis is Cobb angle measurement, but several studies have shown that there is intra- and inter- observer variation in measuring cobb angle manually.Objective: Develop a computer- assisted system to decrease operator-dependent errors in Cobb angle measurement.Methods: The spinal ...
