|Abstract: ||The Generic Graph Machine (GGM) model is a Turing machine-like model for expressing generic computations working directly on graph structures.
In this paper we present a number of observations concerning the expressiveness and complexity of GGMs. Our results comprise the following: (i) an intrinsic characterization of the pairs of graphs that are an input–output pair of some GGM; (ii) a comparison betweenGGMcomplexity and TM complexity; and (iii) a detailed discussion on the connections between the GGM model and other generic computation models considered in the literature, in particular the generic complexity classes of Abiteboul and Vianu, and the Database Method Schemes of Denninghoff and Vianu.|
