Abstract: This paper describes an evolutionary computation based graph rewriting approach to generating classes of
graphs that exhibit a set of desired global features. A set of rules are used to generate, in a constructive
manner, classes of graphs. Each rule represents a transformation from one graph to another. Each of these
transformations causes local changes in the graph. Probabilities can be assigned to the rules which govern the
frequency with which they will be applied. By assigning these probabilities correctly, one can generate graphs
exhibiting desirable global features. However, choosing the correct probability distribution to generate the
desired graphs is not an easy task for certain graphs and the task of finding the correct settings for these graphs
may represent a difficult search space for the evolutionary algorithms. In order to generate graphs exhibiting
desirable features, an evolutionary algorithm is used to find the suitable probabilities to assign to the rules.
The fitness function rewards graphs that exhibit the desired properties. We show, using a small rule base, how
a range of graphs can be generated.(More)
