摘要

本文给出了p=2和p=4的p值输入、二值输出函数的多位置决策图伪kronecker表达式的优化方法。使用扩展真值表的传统方法需要O(3/sup n/)的内存来简化n个变量的表达式，并且只适用于当p=2时n=14个变量的函数。所提出的方法利用并可以优化相当大的问题。给出了最多n=39个变量的实验结果。

Optimization of multiple-valued AND-EXOR expressions using multiple-place decision diagrams

The author presents an optimization method for pseudo-Kronecker expressions of p-valued-input, two-valued-output functions using multiplace decision diagrams for p=2 and p=4. A conventional method using extended truth tables requires memory of O(3/sup n/) to simplify an n-variable expression, and is only practical for functions of up to n=14 variables when p=2. The method presented utilizes and can optimize considerably larger problems. Experimental results for up to n=39 variables are shown.<>
