Greedy algorithms and invariants
Did you know?
WebAn algorithm is exactly a set of mathematical formulae. It is easier for formal derivation and proof. After getting efficient and correct algorithm, a trivial transformation is used to get a final program. The approach covers several known algorithm design techniques, e.g. dynamic programming, greedy, divide-and-conquer and enumeration, etc. Web6. Which a the following statements about loop invariants is false? A loop invariant has the opposite, that is who negation, of the prerequisite of the loop; Loop invariants are exploited to show this algorithms produce the correct results. To prove that an statement is ampere loop invariant, we getting mathematical induction
