Membership Problem with Adjacency Matrix
Computación y Sistemas, 2021In this article, proposed a algorithm to solve the membership problem in Hyperedge Replacement Grammars (HRG). Given a hypergraph H with labeled nodes rooted and directed hyperedges, the problem consists in determining if H 2 L(G), where G is in HRG, this is to say, if H is in the language generated by G, for this the analysis is done directly in the ...

Optical Adjacency Matrix Associative Processor
SPIE Proceedings, 1990A new bidirectional optical associative processor is described for searching a hierarchical database that is stored as an adjacency matrix. The paper discusses how the processor can answer relatively complex queries on a knowledge base when the queries are formulated as combinations of set closures, unions, intersections, and complementations.

A Compact Form of the Adjacency Matrix
Journal of Chemical Information and Computer Sciences, 2000It has been shown that the adjacency matrix can be transformed into a row vector and then into a single number. This number can again be decoded to recover the row vector, and this in turn can be decoded to restore the original adjacency matrix. A special, rather efficient coding scheme was devised for acyclic structures.

Data Clustering by Scaled Adjacency Matrix
2011Similarity based clustering, which is to find the extrinsic clusters in data by taking as input a collection of real-valued similarities between data points, has been playing an important role in data analysis and engineering. Lots of work had been done in this field.

Digital Filters Using Adjacency Matrix Representation
2008An evolutionary algorithm able to synthesize low-sensitivity digital filters using a chromosome coding scheme based on the adjacency matrix is proposed. It is shown that the proposed representation is more flexible than GP-tree schemes and has a higher search space dimension.
