Formalisation, Abstraction and?Refinement of?Bond Graphss are replete with ambiguity, significantly impeding understanding. A formalisation of the essentials of bond graphs is given, together with a formalisation of bond graph transformation, which can directly express abstraction and refinement of bond graphs.

A Rule-Based Procedure for?Graph Query Solvinggraph databases. For this purpose, we first define a graph query algebra where some operations over graphs and sets of graph homomorphisms are specified. Then, the notion of pattern is introduced to represent a kind of recursively defined formula over graphs. The syntax and formal semantics of patte

Implementing the?, Language: A Functional Language with?Graphs as?First-Class Data leaf-linked trees. They can be abstracted into graphs (or more precisely, port hypergraphs). In existing imperative programming languages, these structures are handled with destructive assignments to heaps as opposed to a purely functional programming style. These low-level operations are prone to

We formally define effect-oriented graph transformation, show how matches can be computed without explicitly enumerating all induced classic rules, and report on a prototypica
