基于三角范数的引力搜索算法分析

Analyzing of Gravitational Search Algorithm Based on Triangular Norms

分析了由Esmat Rashedi提出的引力搜索算法(GSA)之后,对万有引力公式进行变换,用三角范数的其他算子代替万有引力公式中两个粒子惯性质量之间的乘法算子。分析不同三角范数算子的二维图像的特征之后,选择了三角范数中的5个算子进行实验。实验结果表明,对于具有一定三维图像特征的测试函数,使用相应三角范数算子的引力搜索算法对其全局搜索的能力相对地好于使用其它三角范数算子的改进引力搜索算法。

To transform universal gravitational formula after analyzing Gravitational Search Algorithm（GSA） Esmat Rashedi proposed,the product operator between two particles＇s inertia quality in the universal gravitation formula ws substituted by other triangular norms operator.Five triangular norms operators were chose for experience after analyzing feature of two-dimensional image to different triangular norms operators.Results show：to a test function having certain three-dimensional image feature,ability to find the global optimum using GSA of corresponding triangular norms operator is relatively better than GSA of others triangular norms operators.
