Edge-clique graphs of cocktail parties have unbounded rankwidth
In an attempt to find a polynomial-time algorithm for the edgeclique cover problem on cographs we tried to prove that the edge-clique graphs of cographs have bounded rankwidth. However, this is not the case. In this note we show that the edge-clique graphs of cocktail party graphs have unbounded rankwidth.
متن کاملGlobal Cocktail Parties and an Arms-Race in Language Evolution
Many species change their signals in response to crowding, consistent with information theoretic accounts of signalling in the presence of noise. In this article we explore the hypothesis that the statistical structure of language has evolved to enhance reception and processing in response to competition in the language market. In particular, we investigate how concreteness has changed over the...
متن کاملMultiple signals and male spacing affect female preference at cocktail parties in treefrogs.
Effective acoustic communication in the face of intense conspecific background noise constitutes a constant sensory challenge in chorusing and colonial species. An evolutionary approach suggests that behavioural and environmental constraints in these species should have shaped signal design and signalling behaviour to enable communication in noisy conditions. This could be attained both through...
متن کاملCommunity noise annoyance risk in two surveys.
Two noise annoyance surveys were performed in Bratislava, the capital of the Slovak Republic, in a ten-year interval (1989-1999). This was a period of political and socioeconomic transformation as well as of changes in traffic management. Equivalent noise levels were assessed at the dormitory (exposed group) and in the residential areas (100 measuring stations) where another group of students (...
متن کاملExternal and internal noise surveys of London primary schools.
Internal and external noise surveys have been carried out around schools in London, UK, to provide information on typical levels and sources to which children are exposed while at school. Noise levels were measured outside 142 schools, in areas away from flight paths into major airports. Here 86% of the schools surveyed were exposed to noise from road traffic, the average external noise level o...
