针对使用遗传算法进行复杂网络社团发现时,存在较强随机性以及容易陷入局部最优解的缺陷,提出一种基于遗传框架的复杂网络社团发现新方法。其通过一次迭代标签传播方法进行种群初始化,针对字符串表示法交叉困难的特点提出了统一标签交叉策略,并采用有指向性的变异策略解决遗传算法随机变异的缺陷问题。实验结果表明:对典型的人工生成网络结构和真实网络结构,该方法能够较准确地发现社团结构;与经典算法进行比较,该方法具有较高的社团发现精度且收敛速度较快。
針對使用遺傳算法進行複雜網絡社糰髮現時,存在較彊隨機性以及容易陷入跼部最優解的缺陷,提齣一種基于遺傳框架的複雜網絡社糰髮現新方法。其通過一次迭代標籤傳播方法進行種群初始化,針對字符串錶示法交扠睏難的特點提齣瞭統一標籤交扠策略,併採用有指嚮性的變異策略解決遺傳算法隨機變異的缺陷問題。實驗結果錶明:對典型的人工生成網絡結構和真實網絡結構,該方法能夠較準確地髮現社糰結構;與經典算法進行比較,該方法具有較高的社糰髮現精度且收斂速度較快。

Against the defects of stronger randomness and local optimal solution when the community detection in complex networks was made using the genetic algorithm, a new method of community detection in complex networks was presented using the genetic algorithm structure. The single-iteration label propagation method was utilized to make population initializing, a strategy of unified label crossover against crossing difficulty of string representation was proposed, and the directional mutation strategy was adopted to solve the defects of random mutation in the ge-netic algorithm. The experimental results show that for the typical computer-generated network structure and real-world network structure, the method can detect community structure more accurately. Compared with the classical algorithms, it has a higher precision of community detection and a faster convergence speed.
