Implementation of graph manipulation under X Window system environment

Abstract

In graph theory graphs are mathematical objects that can be used to model networks, data structures, process scheduling, computations and a variety of other systems where the relations between the objects in the system play a dominant role.We will now consider graphs as mathematically self-contained units with rich structure and comprehensive theory; as models for many phenomena, particularly those arising in computer systems; and as structures which can be processed by a variety of sophisticated and interesting algorithms.For graph theory presentation, we need a very good graphical user interface(GUI) to approach the goal. X Window system is ideally suited for such a purpose. This package program is based on X Window system environment. With this package, we can manipulate graphs by special functions which can put nodes, put edges, delete nodes, delete edges, change the whole graph size, move graph location, and modify edge weights.
