表达式编译分析的Visual Basic实现

Compiling and analyzing of expression string by Visual Basic 6.0

针对通用型优化设计软件中表达式分析与求解的特殊性,利用VisualBasic6.0中的动态数组技术和用户定义类型实现对表达式字符串的编译分析,解决了每次计算目标函数和约束函数表达式都必须重复进行分析的问题;对分析的结果数组进行优化处理,消除了递归调用和重复计算,提高了计算速度.

The implementation and optimization of the compiling of the expression string by using Visual Basic 6.0 dynamic array and user defined type were discussed, and the problem of expression compiling in the field of designing universal visualization optimized software was resolved.
