Examples
- Such ciphers permit length - preserving encryption of a data stream with only a single pass through the data
这些加密方法使得对只有单一输入数据的数据流实施保持长度不变的加密成为可能。 - This paper investigates the closure property of sublogarithmic space - bounded 1 - inkdot alternating pushdown automata with only existential universal states , and shows , for example , that for any function l such that l loglogn and l o , the class of sets accepted by weakly strongly l space - bounded 1 - inkdot two - way alternating pushdown automata with only existential universal states is not closed under concatenation with regular sets , length - preserving homomorphism , and kleene closure
Chandra kozen和stockmeyer提出了交替性alternation作为并行计算的一个理论模型。交替式alternating图灵机是非确定性图灵机的推广，它的状态集合被分为万能状态universal state和存在状态existential state 。非确定性图灵机可看作只有存在状态的交替式图灵机。
