摘要
分析了检测器数目对检测性能的影响,构造了一种基于检测器覆盖率评估的否定选择算法;为了进一步减少冗余检测器,提出了一种检测器集优化方法.仿真实验表明,本文算法能够在保证较高检测率的前提下,降低检测器集规模,从而提供了良好的检测效率,具有较好的理论价值和工程应用价值.
After the effects of detectors on detection performance coverage were studied, a novel negative selection algorithm (NSA) based coverage evaluation was designed. The optimization of detectors was put forward to get rid of redundant detectors. Simulation tests show that the revisited NSA can reduce the number of detectors without reducing detecting rate, and has advantages of good performance, and applying prospect.
