Polynomial - time approximation schemes ( ptas ) : a ptas is a family of algorithm { a | > 0 } such that for any fixed > 0, a runs in time polynomial in the length of the input and gets a solution with an objective value which is at most 1 + e times of the optimum
若每次修正後，實例的目標函數值不超過原來的1 + o （ ）倍，我們稱修正費用不超過1 + o （ ） 。 ptas演算法：若演算法列{ a _ }對于問題的任一個例子都是1 +近似演算法，計算次數是問題大小的多項式（將視為常數） ，稱它為ptas演算法。 -
For the former, the ptas weaken the impact of the discrimination, so it is called as the “ spaghetti bowl ”
