The article challenges the view that the Neo-Darwinian theory of evolutionis sufficient to explain the ongoing evolution. The classical evolutionary algorithmsbased on that theory suffer from the loss of diversity, stagnation andpremature convergence. The author claims that the cosmetic changes of thosetools are not sufficient to overcome this situation and the change of overall theoreticalframework is required. The proposition of a semiotic theory of evolutioncreated by Charles Sanders Peirce is revealed as an alternative to the classicalModern Synthesis. This alternative model of evolution is implemented intwo kinds of evolutionary algorithms: P-EA and SEAM, which simulate evolutionby virtue of cooperation and symbiosis respectively. The new approach toalgorithms constructs shows significant benefits upon classical evolutionaryalgorithms in benchmark tests, which may support the original claim that theaccepted theory of evolution needs rethinking today.
Issues surrounding the nature of the musical sign loom large in the development of a viable musical semeiotic that goes beyond ad hoc or impressionistic appropriations of terminology. This article articulates an understanding of the sign with specific relevance to the analysis of musical topics by rigorously applying Peirce’s semeiotic theory to illuminate the nature of sign functioning in music.
W artykule autor rozważa koncepcje kontinuum oparte na intuicji stworzone przez Giusseppe Veronesa, Paula du Bois-Reymond, Franza Brentano, Charlesa Sandersa Peirca i Henriego Poincarego w odpowiedzi na idee arytmetycznego kontinuum Richarda Dedekinda i Georga Cantora. Stara się znaleźć wspólny czynnik, który łączy pojęcia intuicyjnego kontinuum użyte przez wspomnianych matematyków i filozofów.
