摘要: Abstract Every graph generated by a hyperedge replacement graph-grammar can be represented tree, namely the derivation tree of sequence that produced it. Certain functions on graphs computed recursively trees these graphs. By using monadic second-order logic and semiring homomorphisms, we describe in single formalism large class such functions. Polynomial even linear algorithms constructed for some We unify similar results obtained Takamizawa (1982), Bern (1987), Arnborg (1991) Habel (1989).
