Termination: The loop terminates, and when it terminates, the invariant---usually along with the reason that the loop terminated---gives us a useful property that helps show that the algorithm is correct. 我觉得用中文的一句常见的话然后我再续上一段,可以更好的概括这三个步骤; Initialization: ...
当然,在不影响性能且对暴露报错有良好助益时,完全可以显式的将「循环不变式」的断言放于代码的关键位置。react源码中的invariant函数就被广泛的用来断言「某种不变式」。 Incomputer science, aloop invariantis a property of aprogramloopthat is true before (and after) each iteration. It is alogical ...
The main advantage is that the user does not need a variant or a loop invariant to achieve an automatic proof for finite state event systems.Our approach is illustrated on a protocol between a chip card and a card reader, called protocol T=1 ....
Then using this metric property, we define a very broad loop shortening property for finitely generated groups. Our definition includes Elder's groups, and unlike his definition, our property is obviously a quasi-isometry invariant of the group. Furthermore, all finitely generated groups satisfying ...
A clause can create a loop invariant by a suitable init function with no step, pred, or fini function. This may be useful to "wire" an incoming loop argument into the step or pred function of an adjacent loop variable. If some of the clause functions are virtual methods on an instance...

The experimental result shows the maximum change of the possible \(| {W}_{{{\mathcal{C}}}|\) (from 0 to 2), manifesting the non-Abelian nature of the geometric property. Since the system is time-reversal (TR) invariant (our physical system has a magnetic field present, so TR symmet...
Figure 1.The 3′ end of mammalian histone mRNAs. The 26-nt stem loop sequence at the 3′ end is shown. The nts in red are invariant in mammalian histone mRNAs and are essential for efficient SLBP (stem-loop binding protein) binding to the stem-loop. The position of the cleavage is in...
