| 1. | For the former , the ptas weaken the impact of the discrimination , so it is called as the “ spaghetti bowl ”
本文以“报告”的九章分别作为主题,各自展开讨论。 |
| 2. | 31 - 1 - 2004 : a new year carnival was held at kwun tong amusement park by the federation of ptas in kwun tong district
31 01 2004年观塘区家长教师会联会于观塘游乐场举行家校同欢庆新春嘉年华会。 |
| 3. | In this paper , we design a ptas for the case of identical parallel batch matchines with batch capacity and the number of machines both being constant
给出了当机器台数m及批容量b均为常数情况下的ptas算法 |
| 4. | 2 . polynomial - time approximation schemes ( ptas ) lemma 1 with 1 + cost , we can assume that all processing times and release dates are integer times of 1 +
引理1在修正费用不超过1 。的情况下，可以将原实例的加工时间和到达时间修改为1 。的整数次幂 |
| 5. | Activities it organised in 1999 included a seminar on parent education , various promotion activities and training programmes for ptas as well as a campaign calling upon parents to show appreciation for teachers ' work
年内，委员会举办了一个家长教育研讨会、多项为家长教师会筹办的推广活动及训练课程，以及一项呼吁家长敬师的运动。 |
| 6. | A ptas is designed for the problem when the batch capacity and the number of machines are both constant . 1 . definition and assumption definition l + o ( ) cost : each transformation potentially increases the objective function value by 1 + o ( ) , we shall say it produces 1 + o ( ) cost
在以下两方面发展了brucker ， foto等人的成果，一是工件具有了到达时间和分批加工的复杂状况，二是机器环境有单台机器变为同型机，并给出了它的一个ptas算法。 |
| 7. | 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
若每次修正后，实例的目标函数值不超过原来的1 + o ( )倍，我们称修正费用不超过1 + o ( ) 。 ptas算法：若算法列{ a _ }对于问题的任一个例子都是1 +近似算法，计算次数是问题大小的多项式(将视为常数) ，称它为ptas算法。 |
