Prove the correctness of dynamic programming

Webb6 juni 2024 · Like an a priori proposition in philosophy, the correctness of an algorithm is independent of its execution. In other words, testing cannot guarantee the correctness of algorithms. We need to prove it. Here’s the basic flow of the proof: 1. For all visited vertices, we find the shortest paths. WebbThe point is not that testing is useless! It can be quite effective. But it is a kind of inductive reasoning, in which evidence (i.e., passing tests) accumulates in support of a conclusion (i.e., correctness of the program) without absolutely guaranteeing the validity of that conclusion.(Note that the word “inductive” here is being used in a different sense than …
