摘    要:论文首先简要介绍了人工免疫系统的基本概念,然后着重分析了人工免疫系统中的主要算法“阴性选择算法”,并提出一种r可变阴性选择算法.同传统的阴性选择算法相比,该算法大大减少了不可避免的“黑洞”数量.仿真结果表明:r可变阴性选择算法产生成熟检测器的迭代次数、黑洞数量均大幅下降,同时检测率有显著提高.

关 键 词:人工免疫系统  阴性选择算法  匹配阈值  黑洞

Abstract:The Artificial Immune System (AIS) is introduced briefly, then as one of the main algorithms in AIS, negative selection algorithm is discussed. In order to reduce the number of holes which is inevitable in negative selection algorithm, an algorithm of r-adjustable negative selection algorithm is put forward. The new algorithm can reduce the number of holes through adjusting threshold of matching. The simulation results show that both the number of iteration to generate mature detector and the number of holes decline quickly, while the rate of detecting abnormity raises.
Keywords:artificial immune system  negative selection algorithm  threshold of matching  hole
