摘要
基于一个有充分根据的论证,提出了一个公平终止保护命令的证明规则。该规则被应用于几个例子,并被证明是合理的和(语义上)完整的,即计算树的操作语义。该规则与Lehmann, Pnueli和Stavi(在“Proc. Internat”中)提出的另一条规则有关。自动机语言。和Programming, '81, " Acre, July 1981),通过证明lps规则的(语义)完备性遵循我们的完备性。
A proof rule for fair termination of guarded commands
We present a proof rule for fairly terminating guarded commands based on a well-foundedness argument. The rule is applied to several examples, and proved to be sound and (semantically) complete w.r.t. an operational semantics of computation trees. The rule is related to another rule suggested by Lehmann, Pnueli, and Stavi (in “Proc. Internat. Colloq. Automata Lang. and Programming, '81,” Acre, July 1981), by showing that the (semantic) completeness of the LPS-rule follows from the completeness or ours.
