Although feeding at sites Mexico has long been considered unimportant, observations show that butterflies feed inside outside their forests on sunny days. Nectaring close to hibernation co...
Lévy flight is a random walk mechanism which can make large jumps at local locations with high probability. The probability density distribution of was characterized by sharp peaks, asymmetry, and trailing. Its movement pattern alternated between frequent short-distance occasional long-distance jumps, jump out optimal expand the population search area. metaheuristic algorithms are inspired natu...
