Also, one step in “ step algorithm ”, which takes off one unit of bandwidth away from the virtual path with lowest cbp in the whole network, is explained to be immoderate
同時，對步進式演算法中的一步:對全網中呼叫損失率最小的虛路徑做帶寬減一操作，本文解釋了這個步驟的不合理性。 -
Optimal periodic control with the lowest operational cost by limiting total substrate discharge mass was studied. through adding new state variable and using supplement functions, the problem with restriction conditions was converted into nonrestriction problem. in addition, the dynamic searching method of optimal step coefficient was developed to modify the conventional gradient method, consequently the calculation problem of the multivariable optimal periodic control was able to be resolved better. it was found that the operational costs of optimal control under various initial states are distinctly different. a new concept of optimal control under optimal initial state was presented. it is pointed out emphatically that to the treatment system without optimal control condition, the suboptimal control with extensive practical value can be realized according to the results of optima control
著重研究了在限制有機物排放總量時，使其運行費用最低的最優周期控制問題.通過增加新的狀態變量和用補償函數法，將本課題的有約束條件問題化為無約束條件問題，並提出了最優步長參數的動態搜索法來修改傳統的梯度法，從而較完善地解決了多變量最優周期控制的計算問題.研究中還發現了不同初始條件下最優控制所需要的運行費用也大不相同，進而提出了最優初始狀態下最優周期控制的新概念，這對保證出水質量的同時進一步降低污水處理成本來說具有更重要的意義.本文還強調指出：對于尚不具備實現最優控制條件的處理系統，可根據最優控制的研究結果實現具有廣泛實用價值的準最優控制 -
In the solution, the 0 - 1 integer and real number mixed encoding technique was employed to describe an artificial fish ; behaviors of a fish were dispatched by its body energy status ; the following behavior was described by the greedy method where moving step is direct ratio to a fish ' s hungry degree ; the lowest survival body energy controlling technique was used to realize escaping policy from locally optimum positions ; the maximum iterating times and the changing degree of the optimum solutions during iterating were used to control the terminating time
在解算過程中，人工魚個體採用0 - 1整數和實數混合編碼方法描述；用人工魚體能累計和消耗程度來調度其行為；採用與饑餓程度成正比的移動步距的貪婪法描述個體追尾行為；採用最低生存體能控制來實現局部最優解逃逸策略；採用最大迭代次數和迭代過程中最優解平均值變化程度來控制迭代終止時機。 -
It is always a paradox to improve the performance of tracking initialization and to reduce its time cost, through tracking initializationhas been divided into different ranks to which we have different treatment, initializing fleetly for high rank, waiting to the next one or two step to initialize for lower ranks, non - initializing for the lowest ranks. the result of simulation shows that this method accelerates the average initialization velocity with certain probability of initialization and false initialization
航跡起始質量與航跡起始時間的矛盾一直是難以解決的問題，通過引入航跡起始等級化的方法，不同等級的起始航跡區別對待，等級高的航跡快速起始，等級較低的航跡延遲一步（或兩步后）起始，等級最低的航跡暫時不起始。模擬結果表明，此方法在保證一定航跡起始概率與虛假航跡概率的情況下，加快了平均起始速度。 -
When control is maintained, treatment can be stepped down in order to find the lowest step and dose of treatment that maintains control
