摘要: 针对检测器集生成速率不高的问题,提出一种改进的混沌否定选择算法。由于Logistic映射折叠次数有限,采用自映射产生的混沌序列,改进混沌二值序列的产生方法。实验结果表明,该算法具有较好的混沌特性,能有效提高检测器集的生成速度,较好地覆盖检测空间,安全性较强。

关键词: 否定选择算法, 混沌特性, 自映射

Abstract: In order to improve the detector collection of generation rate, this paper proposes a kind of improvement chaos negative selection algorithm. Because the Logistic map fold number of times is limited, it uses the chaos sequence which produces from self-map to have a better chaos characteristic. The new algorithm can enhance the production speed of detector collection effectively, cover the examination space well, and has better security.

Key words: negative selection algorithm, chaos characteristic, self-map
