Yangtze Finless Porpoise Optimization Algorithm

To address the problems of existing swarm intelligence optimization algorithms, such as limited search information structure, reliance on mean statistics for group collaboration, and susceptibility to premature convergence, this paper proposes a novel swarm intelligence optimization method—the Yangtze Finless Porpoise Optimization Algorithm.

Origin of the double- and multi-pulse structure of echolocation signals in Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientialis)

, 2005
The signals of dolphins and porpoises often exhibit a multi-pulse structure. Here, echolocation signal recordings were made from four geometrically distinct positions of seven Yangtze finless porpoises temporarily housed in a relatively small, enclosed ...
