Based on the randomized method , a randomized method with pretreatment is obtained for the design problem of fir digital filters with discrete coefficients 結合隨機擾動方法,得到了求解離散系數濾波器設計問題的一種帶預處理的隨機擾動算法。
Compared with the conventional randomized method , the randomized method with pretreatment often yields a better sub - optimal performance and costs less cpu time 與隨機擾動方法相比,帶預處理的隨機擾動方法得到的次優解的性能更好,需要的時間也大大減少。
Students lead most of the class sessions in 15 . 099 , using the conference - quality presentations they have created . course readings revolve around this term ' s topic , randomized methods for deterministic optimization 在15 . 099課程中,大部分的課時由學生來領導,使用學生自己做的達到學術會議標準的陳述報告。課程閱讀圍繞這學期的主題:確定性最佳化的隨機方法。
In contrast to conventional optimization algorithms whose iterates are computed and analyzed deterministically , randomized methods rely on stochastic processes and random number / vector generation as part of the algorithm and / or its analysis 傳統的最優化算法中迭代的計算和分析是確定的,與之相比,隨機方法依靠隨機過程和隨機數字/向量的生成作為算法和(或)算法分析的一部分。
In keeping with the tradition of the last twenty - some years , the readings in optimization seminar will focus on an advanced topic of interest to a portion of the mit optimization community : randomized methods for deterministic optimization 與過去20多年的傳統一致,最佳化書報討論課程的重點將放在麻省理工學院一部分最佳化團體感興趣的一個高級主題上:確定性最佳化的隨機方法。
In contrast to conventional optimization algorithms whose iterates are computed and analyzed deterministically , randomized methods rely on stochastic processes and random number / vector generation as part of the algorithm and / or its analysis 傳統的最佳化演算法中迭代的計算和分析是確定的,與之相比,隨機方法依靠隨機過程和亂數字/向量的生成作為演算法和(或)演算法分析的一部分。
An equivalent integral programming model and a new semidefinite programming relaxation for the max - bisection problem are given . then , we solve the relaxation with a projected gradient algorithm . coupled with the randomized method , an approximate solution of the max - bisection problem is obtained 2 .給出圖的最大二等分問題的整數規劃模型的等價模型及其新的半定規劃松弛模型,利用投影梯度算法求解該半定規劃松弛模型,然后利用隨機擾動算法求得原問題的次優解
