萤火虫算法
此条目需要扩充。 (2013年5月19日) |
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。[2]
算法描述
萤火虫算法的伪代码可以概括为:
Begin 1)目标函数 2)生成一个萤火虫的初始人口 3)制定光照强度 ,因此,它与 (例如,对于最大化问题 或 ; 4)定义吸收系数 while(T < MaxGeneration) for i =1:n(所有n萤火虫) for j =1:n(n萤火虫) if( ), 移动萤火虫i向j; end if 吸引力与距离 ; 评估新的解决方案和更新的光强度; end for j end for i 排名萤火虫和找到当前最佳; end while 处理后的结果和可视化; end
对于任何一两只萤火虫的主要更新公式 and 是
其中 是步长参数, e 是一个矢量(服从高斯或其他的分布)。
可以证明在 的情况,FA可以简化为 准粒子群优化(PSO).事实上,,如果内环(j)条被删除,亮度 替换为当前的全球最佳 ,FA基本上成为标准PSO。
萤火虫算法的变种
离散萤火虫算法(DFA)
离散形式的萤火虫算法(Discrete Firefly Algorithm,DFA)[3] DFA优于现有算法如蚁群算法。
对于图像分割,基于FA-方法比Otsu的方法更为有效.[4] 同时, 离散萤火虫算法对QAP问题,Durkota已进很好的实现行[5]
针对负荷预测中的特征选择问题,应用FA实现Wrapper特征选择算法. [6]
多目标萤火虫算法
Apostolopoulos and Vlachos对FA进行了一个重要的多目标研究[7]。同时,Yang提出了多目标萤火虫算法(Multiobjective Firefly Algorithm,MOFA),对连续优化问题有很好的效果[8]。
拉格朗日FA
拉格朗日萤火虫算法用来解决电力系统优化单元承诺问题[9]。
混沌FA
混沌萤火虫算法(Chaotic Firefly Algorithm,CFA)也显示了算法的有效性[10]。
混合算法
萤火虫算法与蚁群优化算法相结合的混合算法,能够解决金融投资组合优化 [11]。
基于萤火虫算法的 Memetic 算法
一种基于萤火虫算法(FA)的Memetic算法(FA-MA)被用来优化支持向量机(SVR)预测模型的参数。在该FA-MA中,FA用来搜索全局解空间,而模式搜索(pattern Search) 被用来进行个体学习和局部解空间搜索。[12]
实际应用
萤火虫算法已被应用到几乎所有领域科学和工程,如数字图像压缩和图像处理[13][14],特征值优化[15],特征提取和故障检测[16][17],天线设计[18][19],工程结构设计[20], 调度和旅行商问题[21][22][23],语义组成[24],化学相平衡[25], 聚类[26],动态问题[27][28], 刚性图像配准问题[29],参数选择[30][12],蛋白质折叠问题[31]等等。
