摘要: 就主动数据库中规则冲突这个问题进行了研究,结合遗传算法,提出了一种规则调度的新算法—基于遗传算法的ECA规则的调度算法。该算法把规则的优先级与主动数据库中知识模型的维度相结合,给出了一种合理的编码策略,构造了一个量化函数作为适应度函数,对遗传算子进行了改进,有效避免了早熟现象的发生;最后给出了这个算法,并就其正确性和复杂度进行了证明。
Abstract: ECA rules collision are studied in this paper,and proposes a new ECA rules scheduling algorithm—ECA rules scheduling algorithm based on Genetic Algorithm.The algorithm combines priority and knowledge model in ACDB and presents a fit encoding strategy,constructs a measure function as fitness function,genetic operator is improved and prevent prematurity phenomena.At last,the algorithm is presented,and its correctness and complexity are proved too.
