Graph transformation

Graph transformation, or Graph rewriting, concerns the technique to create a new graph out of an original graph using some automatic machine. It has numerous applications, ranging from software verification to layout algorithms.

Graph transformations can be used as a computation abstraction. The basic idea is that the state of a computation can be represented as a graph, further steps in that computation can then be represented as transformation rules on that graph. Such rules consist of an original graph, which is to be matched to a subgraph in the complete state, and a replacing graph, which will replace the matched subgraph.
