Algebraic Graph Rewriting Using a Single Pushout
نویسنده
چکیده
We show how graph rewriting can be described with a single pushout in a suitable category of graphs, and compare our result with the conventional approach which uses double pushouts.

Algebraic Transformation of Unary Partial Algebras I: Double-Pushout Approach
The transformation of total graph structures has been studied from the algebraic point of view over more than two decades now, and it has motivated the development of the so-called double-pushout and single-pushout approaches to graph transformation. In this article we extend the double-pushout approach to the algebraic transformation of partial many-sorted unary algebras. Such a generalization...
متن کاملAlgebraic Approach to Single-Pushout Graph Transformation
The single-pushout approach to graph transformation interprets a double-pushout transformation rule of the classical algebraic approach which consists of two rotul graph morphisms as a single particll morphism from the left-to the right-hand side. The notion of a double-pushout diagram for the transformation process can then be substituted by a single-pushout diagram in an appropriate category ...
متن کاملLNCS 4178 - Sesqui-Pushout Rewriting
Sesqui-pushout (sqpo) rewriting—“sesqui” means “one and a half” in Latin—is a new algebraic approach to abstract rewriting in any category. sqpo rewriting is a deterministic and conservative extension of double-pushout (dpo) rewriting, which allows to model “deletion in unknown context”, a typical feature of single-pushout (spo) rewriting, as well as cloning. After illustrating the expressivene...
متن کاملThe Contractum in Algebraic Graph Rewriting
Algebraic graph rewriting, which works by first removing the part of the graph to be regarded as garbage, and then gluing in the new part of the graph, is contrasted with term graph rewriting, which works by first gluing in the new part of the graph (the contractum) and performing redirections, and then removing garbage. It is shown that in the algebraic framework these two strategies can be re...
