- A note on non - closure property of sublogarithmic space - bounded 1 - inkdot alternating pushdown automata with only existential universal states
因为它们为计算机科学理论的研究提供了一个基本的思想和数学模型。 - 13 yoshinaga t , xu j , inoue k . a note on closure property of sublogarithmic space - bounded 1 - inkdot alternating turing machines with only existential universal states
例如，关系在关系代数运算下的结果仍为关系，我们称关系集合在关系代数运算下封闭。 - Through calculation of a living example and its result analysis verified that while the vibration amplitude is comparatively small and the sine curve is being adopted , the theoretical contour of cam possesses rather good form closure property and is suitable to be applied for high - speed cam
通过实例计算和结果分析，表明该凸轮理论廓线采用正弦曲线，在振幅较小时，有较好的形封闭性，适合用于高速凸轮。 - 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。
