An improved grey wolf algorithm and its localization research in complex indoor environments
Scientific ReportsIn complex indoor environments, traditional localization methods often suffer from non-line-of-sight (NLOS) and multipath problems, which lead to unsolvable or incorrectly solved mathematical localization models, thereby limiting localization accuracy. A

Canadian Anaesthetists’ Society Journal, 1963 The inflammability of intestinal gases was demonstrated by Vulparious in the seventeenth century. The main gases incriminated are methane and hydrogen and their production is increased by a leguminous diet or by excessive fermentation in cases of pyloric stenosis with gross gastric stasis.
