EnglishAbstract
A way of generating cocyclic Hadamard matrices is described, which combines a new heuristic, coming from a novel notion of fitness, and a peculiar local search, defined as a constraint satisfaction problem. Calculations support the idea that finding a cocyclic Hadamard matrix of order 4 · 47 might be within reach, for the first time, progressing further upon the ideas explained in this work.Junta de Andalucía FQM-01
