Graph design by graph grammar evolution [PDF]

open access: yes2007 IEEE Congress on Evolutionary Computation, 2007
Determining the optimal topology of a graph is pertinent to many domains, as graphs can be used to model a variety of systems. Evolutionary algorithms constitute a popular optimization method, but scalability is a concern with larger graph designs. Generative representation schemes, often inspired by biological development, seek to address this by ...

Context-free path querying with all-path semantics using matrices with sets of intermediate vertices [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2021
The study considers the problem of context-free path querying with all-path query semantics. This problem consists in finding all paths of the graph, the labels on the edges of which form words from the language generated by the input context-free ...

Parsing Graphs with Regular Graph Grammars [PDF]

open access: yesProceedings of the 6th Joint Conference on Lexical and Computational Semantics (*SEM 2017), 2017
Recently, several datasets have become available which represent natural language phenomena as graphs. Hyperedge Replacement Languages (HRL) have been the focus of much attention as a formalism to represent the graphs in these datasets. Chiang et al.

Graph parsing with s-graph grammars [PDF]

open access: yesProceedings of the 53rd Annual Meeting of the Association for Computational Linguistics and the 7th International Joint Conference on Natural Language Processing (Volume 1: Long Papers), 2015
A key problem in semantic parsing with graph-based semantic representations is graph parsing, i.e. computing all possible analyses of a given graph according to a grammar. This problem arises in training synchronous string-to-graph grammars, and when generating strings from them. We present two algorithms for graph parsing (bottom-up and top-down) with

Hypergrammar Based Parallel Multi-Frontal Solver For Grids With Point Singularities

open access: yesComputer Science, 2015
This paper describes the application of hypergraph grammars to drive linear computationalcost solver for grids with point singularities. Such graph grammar productions are the rstmathematical formalism used to describe solver algorithm and each of them ...

FAIR and Interactive Data Graphics from a Scientific Knowledge Graph

open access: yesScientific Data, 2022
Graph databases capture richly linked domain knowledge by integrating heterogeneous data and metadata into a unified representation. Here, we present the use of bespoke, interactive data graphics (bar charts, scatter plots, etc.) for visual exploration ...

A Demonstration of the Grrr Graph Rewriting Programming Language [PDF]

open access: yes, 2000
This paper overviews the graph rewriting programming language, Grrr. The serial graph rewriting strategy is detailed, and key elements of the user interface are described.

A Solution to the Flowgraphs Case Study using Triple Graph Grammars and eMoflon [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
After 20 years of Triple Graph Grammars (TGGs) and numerous actively maintained implementations, there is now a need for challenging examples and success stories to show that TGGs can be used for real-world bidirectional model transformations.

Improving the graph grammar parser of Rekers and Schürr [PDF]

open access: yes, 2011
Graph grammars and graph grammar parsers are to visual languages what string grammars and parsers are to textual languages. A graph grammar specifies a set of valid graphs and can thus be used to formalise the syntax of a visual language. A graph grammar
