Artículo Hadamard Matrices with Cocyclic Core Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Osuna Lucena, Amparo (MDPI, 2021) Since Horadam and de Launey introduced the cocyclic framework on combinatorial designs in the 1990s, it has revealed itself ...
Artículo On Cocyclic Hadamard Matrices over Goethals-Seidel Loops Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Falcón Ganfornina, Raúl Manuel; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Osuna Lucena, Amparo (MDPI, 2020) About twenty-five years ago, Horadam and de Launey introduced the cocyclic development of designs, from which the notion ...
Artículo Generating binary partial Hadamard matrices Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Falcón Ganfornina, Raúl Manuel; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Osuna Lucena, Amparo (Elsevier, 2019) This paper deals with partial binary Hadamard matrices. Although there is a fast simple way to generate about a half (which ...
Artículo A Mixed Heuristic for Generating Cocyclic Hadamard Matrices Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Falcón Ganfornina, Raúl Manuel; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Osuna Lucena, Amparo (Springer, 2018) A way of generating cocyclic Hadamard matrices is described, which combines a new heuristic, coming from a novel notion ...
Artículo GA Based Robust Blind Digital Watermarking Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Martín García, Elena; Osuna Lucena, Amparo (Elsevier, 2018) A genetic algorithm based robust blind digital watermarking scheme is presented. The experimental results show that our ...
Ponencia Generating partial Hadamard matrices as solutions to a Constraint Satisfaction Problem characterizing cliques Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Falcón Ganfornina, Raúl Manuel; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Osuna Lucena, Amparo (2017) A procedure is described looking for partial Hadamard matrices, as cliques of a particular subgraph Gt of Ito’s Hadamard ...
Artículo On D4t-Cocyclic Hadamard Matrices Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Osuna Lucena, Amparo (Wiley, 2016) In this paper, we describe some necessary and sufficient conditions for a set of coboundaries to yield a cocyclic Hadamard ...
Ponencia Searching for partial Hadamard matrices Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Martín García, Elena; Osuna Lucena, Amparo (Universidade de Santiago de Compostela, Servicio de Publicaciones, 2010) Three algorithms looking for pretty large partial Hadamard ma- trices are described. Here “large” means that hopefully ...
Ponencia ACS Searching for D4t-Hadamard Matrices Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Martín García, Elena; Osuna Lucena, Amparo (Springer, 2010) An Ant Colony System (ACS) looking for cocyclic Hadamard matrices over dihedral groups D4t is described. The underlying ...
Ponencia A Heuristic Procedure with Guided Reproduction for Constructing Cocyclic Hadamard Matrices Álvarez Solano, Víctor; Frau García, María Dolores; Osuna Lucena, Amparo (Springer, 2009) A genetic algorithm for constructing cocyclic Hadamard matrices over a given group is described. The novelty of this ...
Ponencia Rooted Trees Searching for Cocyclic Hadamard Matrices over D4t Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Frau García, María Dolores; Gudiel Rodríguez, Félix; Osuna Lucena, Amparo (Springer, 2009) A new reduction on the size of the search space for cocyclic Hadamard matrices over dihedral groups D4t is described, in ...
Ponencia Error correcting codes from quasi-Hadamard matrices Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Frau García, María Dolores; Martín García, Elena; Osuna Lucena, Amparo (Springer, 2007) Levenshtein described in [5] a method for constructing error correcting codes which meet the Plotkin bounds, provided ...
