I Paths and Chains of Random Straight-line Segment
Classical problems associated with paths composed of straight line segments with independent orientations, which have a continuous distribution, are discussed. ~ment formulas are obtained for the distance between initial and terminal points, and a new approximation discussed. The Rayleigh approximation is used to derive approximations to other characteristics of the random path.
متن کاملIndexing Straight-Line Programs∗
Straight-line programs offer powerful text compression by representing a text T [1, u] in terms of a context-free grammar of n rules, so that T can be recovered in O(u) time. However, the problem of operating the grammar in compressed form has not been studied much. We present the first grammar representation able of extracting text substrings, and of searching the text for patterns, in time o(...
متن کاملStraight Line Triangle Representations
A straight line triangle representation (SLTR) of a planar graph is a straight line drawing such that all the faces including the outer face have triangular shape. Such a drawing can be viewed as a tiling of a triangle using triangles with the input graph as skeletal structure. In this paper we present a characterization of graphs that have an SLTR. The charcterization is based on flat angle as...
متن کاملStraight-Line Drawing of Quadrangulations
This article introduces a straight-line drawing algorithm for quadrangulations, in the family of the face-counting algorithms. It outputs in linear time a drawing on a regular W×H grid such that W+H = n − 1 −∆, where n is the number of vertices and ∆ is an explicit combinatorial parameter of the quadrangulation.
