چکیده

We give a linear-time algorithm to decide whether a graph has a planar LL-drawing, i.e. a planar drawing on two parallel lines. This has previously been known only for trees. We utilize this result to obtain planar drawings on three lines for a generalization of bipartite graphs, also in linear time.

Layered Drawings of Directed Graphs in Three Dimensions

We introduce a new graph drawing convention for 3D layered drawings of directed graphs. The vertex set is partitioned into layers with all edges pointing in the same direction. The layers occupy parallel planes and vertices in each layer occupy two parallel lines. Thus, the traditional 2D layered drawing of a directed graph is split into two vertical walls each containing a 2D layered drawing. ...

Two Algorithms for Three Dimensional Orthogonal Graph Drawing

We use basic results from graph theory to design two algorithms for constructing 3-dimensional, intersection-free orthogonal grid drawings of n vertex graphs of maximum degree 6. Our first algorithm gives drawings bounded by an O(x/~ ) • O(x/~ • O(v~ ) box; each edge route contains at most 7 bends. The best previous result generated edge routes containing up to 16 bends per route. Our second al...

Optimal three-dimensional orthogonal graph drawing in the general position model

Let G be a graph with maximum degree at most six. A three-dimensional orthogonal drawing of G positions the vertices at grid-points in the three-dimensional orthogonal grid, and routes edges along grid lines such that edge routes only intersect at common end-vertices. In this paper, we consider three-dimensional orthogonal drawings in the general position model; here no two vertices are in a co...

META-HEURISTIC ALGORITHMS FOR MINIMIZING THE NUMBER OF CROSSING OF COMPLETE GRAPHS AND COMPLETE BIPARTITE GRAPHS

The minimum crossing number problem is among the oldest and most fundamental problems arising in the area of automatic graph drawing. In this paper, eight population-based meta-heuristic algorithms are utilized to tackle the minimum crossing number problem for two special types of graphs, namely complete graphs and complete bipartite graphs. A 2-page book drawing representation is employed for ...

A New Heuristic Algorithm for Drawing Binary Trees within Arbitrary Polygons Based on Center of Gravity

Graphs have enormous usage in software engineering, network and electrical engineering. In fact graphs drawing is a geometrically representation of information. Among graphs, trees are concentrated because of their ability in hierarchical extension as well as processing VLSI circuit. Many algorithms have been proposed for drawing binary trees within polygons. However these algorithms generate b...
