| Outline of Final Research Achievements |
In this research, we have presented algorithms for finding an orthogonal drawing of a hierarchical graph. In an orthogonal drawing, each edge is drawn as a path consisting of vertical and horizontal line segments. The proposed algorithms include the following methods: (i) an algorithm for sharing dummy vertices, (ii) a method for creating hyperedges from the set of edges of the resultant graph, (iii) a method for determining the x-coordinates of the vertices so that the total sum of the lengths of horizontal line segments becomes small, and (iv) an algorithm for drawing hyperedges. The last algorithm (iv) uses at most two horizontal line segments to draw each hyperedge and can make the number of edge crossings in the graph drawing small.
