  • firefly_simple
    萤火虫算法(Firefly Algorithm)是一种启发式算法,灵感来自于萤火虫闪烁的行为。萤火虫的闪光,其主要目的是作为一个信号系统,以吸引其他的萤火虫。剑桥大学的Xin-She Yang(音译:杨新社)教授提出了萤火虫算法,其假设为[1]: 萤火虫不分性别,这样一个萤火虫将会吸引到所有其他的萤火虫 吸引力与它们的亮度成正比,对于任何两个萤火虫,不那么明亮的萤火虫被吸引,因此移动到更亮的一个,然而,亮度又随着其距离的增加而减少 如果没有比一个给定的萤火虫更亮的萤火虫,它会随机移动。 亮度应与目标函数联系起来。萤火虫算法是以自然为灵感的启发式优化算法(The Firefly Algorithm (are) Algorithm is a kind of heuristic Algorithm, inspired by the behavior of the fireflies flash. Fireflies flash, its main purpose is to as a signaling system, to attract other fireflies. The university of Cambridge, Xin- She Yang (transliteration: Yang Xinshe) professor firefly algorithm is proposed, its hypothesis in [1]. Fireflies regardless of gender, such a firefly will attract all the other fireflies Attractive proportional to their brightness, for any two fireflies, less bright fireflies are attracted, so moving to a brighter, however, brightness and reduce with the increase of the distance If there is no more than a given fireflies light of fireflies, it will move randomly. Brightness should be linked with the objective function. The firefly algorithm based on natural inspiration of heuristic optimization algorithm)
