Resumen de Drawing Network Graphs and Digraphs with DERIVE 5

Peter Schofield

• The Users Folder of DERIVE 5.03 contains a Utility/Demonstration File NGRAPHS5.DFW which provides utilities and demonstrations for drawing network graphs and digraphs with DERIVE. Graphs can be drawn in the 2D-plol window from algebraic DRAW instructions using a specification for the coordinates of their vertices together with an edge set (or an adjacency matrix or an adjacency list). By combining basic concepts of a network graphs with DERIVE's powerful algebraic and 2D-plotting facilities a surprisingly powerful set of network graph drawing tools can be produced. This paper describes some activities that I have used will, College degree course students for them to acquire the skills and techniques for constructing network graph drawings with DERIVE.
