摘要
根据对自定义财务指标进行分析与计算的需要,对常规的算符优先移进——归约算法作了一定的改进,使其省略了以语法树形式输出的中间结果,而直接产生逆波兰后缀式,从而实现了对自定义财务指标的分析,并提高了其计算效率,使整个财务分析系统取得了良好的运行效果。
According to the analysis and computation of the self-defining financial index, a modified operator prior shift-reduce algorithm is presented. Compared with the regular one, the modified algorithm produces the postfix expression directly without the middle output in form of a syntax tree. As a result, the modified algorithm improved the system computing efficiency and made the whole financial analysis system achieve an excellent performance.
