分布式遗传算法在智能组卷中的Web services实现

Intelligent test paper with distributed genetic algorithm realizing on Web services

研究了分布式并行遗传算法的智能组卷问题。设计了在校园网范围内的分布式Web服务的组卷系统,通过多线程的软件结构实现了Web服务之间的相互调用及反馈机制,采用基于Base64的预先基因压缩方案来提高SOAP性能。仿真试验证明了分布式Web服务的组卷系统不仅可以极大地减少组卷时间、具有良好的容错能力,同时也能一次生成多套试卷,为构建B/S模式下的机器考试系统提供了依据。

To solve the problem of intelligent test paper with distributed paralleling genetic algorithm,this paper designed the Web service-based test paper auto-generating system running in campus network with multithreading software structure.It realized procedure calling and possessing feed-back mechanism between Web services,improved the SOAP performance with the Base64 encoding compress method.Experimental results validate this system not only having the power of fault-tolerant and reducing the time in working out,but also being able to generate more than one test papers once.This study can provide the reference to developing machine test system running in B /S mode.
