Integrating Graph Rewriting and Standard Software Tools

OptimixJ is a graph rewrite tool that can be embedded easily into the standard software process. Applications and models can be developed in Java or UML and extended by graph rewrite systems. We discuss how OptimixJ solves several problems that arise: the model-ownership problem, the embedded graphs problem, the library adaptation problem, and the target code encapsulation problem. We also show...

Application-oriented Spatial Graph Grammars

The Reserved Graph Grammar (RGG) is a general graph grammar Jormalism that expresses a wide range oj visual languages, This paper presents an extension to RGG with the capability oj spatial specification, Graph transJormation satisfying the spatial specification can be performed in the process oj parsing. The RGG with spatial specification can be applied to various types oj applications, The pa...

Standard Noether normalizations of the graph subring

In this paper, we confirm a conjecture of Alcántar by showing that graph subrings always admit standard Noether normalizations.

Graph Based Heuristics : Beating the LRU Standard ?

In this paper we devise new paging heuristics motivated by the access graph model of paging 2]. Unlike the access graph model 2, 7, 4] and the related Markov paging model 8] our heuristics are truly on-line in that we do not assume any prior knowledge of the program just about to be executed. The Least Recently Used heuristic for paging is remarkably good, and is known experimentally to be supe...
