WebThe previous correctness proof relies on a property of MSTs called the cut property: Theorem (Cut Property): Let (S, V – S) be a nontrivial cut in G (i.e. S ≠ Ø and S ≠ V). If (u, v) is the lowest-cost edge crossing (S, V – S), then (u, v) is in every MST of G. Proof uses an exchange argument: swap out the 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…
