洪捷1-9 98年交大資工 We abuse the "+" operator with the asymptotic notations. For example, we may s ay that the total time for an algorithm is O(n)+θ(n). Which two of following statements are true. c.)O(nlogn)+θ(nlogn)=O(nlogn) 答案是說這個選項是FALSE,為什麼呢? 其中 b.)O(n^2)+θ(n^2)=θ(n^2) 這個選項是TRUE 那麽也肯定O(nlogn)+θ(nlogn)=θ(nlogn) 竟然滿足這個函式被bound在nlog,不也代表是O(nlogn)嗎?
