WebSep 5, 2024 · The correctness of such an algorithm is proved through the loop invariant property. It involves three steps: Steps to prove loop invariant property. Initialization: Conditions true before the first iteration of the loop. Maintenance: If the condition is true before the loop, it must be true before the next iteration. In theoretical computer science, an algorithm is correct with respect to a specification if it behaves as specified. Best explored is functional correctness, which refers to the input-output behavior of the algorithm (i.e., for each input it produces an output satisfying the specification). Within the latter notion, partial correctness, requiring that if an answer is returned it will be correct, is distinguished from total correctness, which additionally requires that an answer is eventually r… logitech 1500 laser cordless desktop manual
