基于VC++6.0和数据库的案例推理认知引擎

Cognitive Engine of Case-Based Reasoning Based on VC ++ 6.0 and SQL

摘要: 针对基于案例推理的动态资源分配的实际应用问题，本文利用SQL2008数据库存储案例、多目标优化结果以及效益函数，在MFC界面上动态显示优化过程。VC++6.0选用ADO数据库访问技术访问SQL2008数据库，对案例子库的数据进行遍历，选择与环境子库中最为匹配的执行方案，执行优化算法，最后将优化后的参数配置送至数据库输出模块，同效用值一起更新案例子库。实践证明本方案灵活有效，可以动态选择优化算法，进行案例更新、优化过程，成功地实现了认知无线电资源动态分配的问题。

Abstract:  

This paper aims to use the cases of SQL 2008 database storage, multi-objective optimization results and eco- nomic benefit of functions, to solve the application problems of dynamic resource allocation based on case-based rea- soning with optimization process displayed dynamically in MFC interface. VC++6.0 visit SQL2008 database by ADO database access technology, go through the date in case database, choose the execution plan most matching with envi- ronmental database, implement the optimization algorithm, sent the optimized parameters configuration to database output module, and finally update case database by optimized parameters and utility value. Practice shows that this scheme is effective because it can select optimization algorithm dynamically, conduct case update and optimization pro- cedure and it leads to the dynamic resource allocation of cognitive radio.
