Buss ${\textbf{NC}}^1 $算法的新方法[Proc. 19 th ACM Symposium on Theory of Computing,Association for Computing Machinery,纽约,1987,pp. 123-131]的布尔公式的评价。这个问题被证明是完全的${\textbf{AC}}^0 $$减少${\textbf{NC}}^1 $。然后,这种方法被用来解决更一般的问题,评估算术公式使用算术电路。
A new approach to Buss’s ${\textbf{NC}}^1 $ algorithm [Proc. 19th ACM Symposium on Theory of Computing, Association for Computing Machinery, New York, 1987, pp. 123–131] for evaluation of Boolean formulas is presented. This problem is shown to be complete for ${\textbf{NC}}^1 $ over ${\textbf{AC}}^0 $ reductions. This approach is then used to solve the more general problem of evaluating arithmetic formulas by using arithmetic circuits.
