摘要: Labelled graphs of bounded degree, with numbers assigned to the arcs at each node, are called d-graphs. A class generalized automata, cellular d-graph in which intercell connections define a d-graph, is introduced. It can be shown that automaton measure various properties its underlying graph; detect graph or subgraph isomorphism; and recognize basic types graphs. Most these tasks performed time proportional diameter given graph. Closure languages also briefly discussed.
