loop invariants 此仓库用于在 issues 中记录自己使用「循环不变式」视角整理的算法题解。当然,所依据的算法思想是不可缺少的。但我题解中会大概率不说,少说。默认读者已经有所了解。 换言之,此仓库的题解特色是:立足于各种算法思想之上,系统记录、整理使用「循环不变式」的题解方案。

In the example, a new tuple is created and initialized for each iteration of the loop. Notice that only thevaryattribute changes in the loop. So instead of creating the tuple in the loop, you can create it outside of the loop. Then, for each iteration of the loop you can set thevary...

The loop-invariant computations are invoked on demand when the need for a stronger loop invariant arises, which allows a gradual increase in the level of precision used by the abstract interpreter. The technique generates loop invariants that are specific to a subset of a program's executions, ...
