Webquadratic inequality invariant (n ≥ a2) is suicient to verify that the inal value ofa is between ⌊sqrt(n)⌋ and ⌈sqrt(n)⌉. Figure 1. Example problems demonstrating the challenges of nonlinear loop invariant learning. We use G-CLNs with Fractional Sampling and PBQUs to develop a uniied approach for general nonlinear loop invariant ... WebThe invariant for linear search is that every element before i is not equal to the search key. A reasonable invariant for binary search might be for a range [low, high), every element before low is less than the key and every element after high is greater or equal.
