In recent years , people introduced powerful mathematical programming into the design of smps to achieve the best design . it forms the mathematical optimization technology of the smps 近年來,人們引入功能強(qiáng)大的數(shù)學(xué)規(guī)劃方法來解決開關(guān)電源的最優(yōu)設(shè)計問題,從而形成了以數(shù)學(xué)規(guī)劃為基礎(chǔ)的開關(guān)電源最優(yōu)設(shè)計技術(shù)。
The mathematical programming methods , both the method of moving asymptotes ( mma ) belonging to convex programming methods and the sequential linear programming method ( slp ) , were used to solving optimization problems 用移動漸進(jìn)線方法( mma )求解單目標(biāo)優(yōu)化問題,用序列線性規(guī)劃方法( slp )求解模糊目標(biāo)混合規(guī)劃問題。
Dual mathematical programming is used to map the original problem exactly and the second approximation of the dual problem is set up by taylor ' s expand form , it is solved by qp ( quadratic programming ) solving device 用對偶數(shù)學(xué)規(guī)劃精確映射原問題,用泰勒展式建立對偶問題的二階近似。最后用二次規(guī)劃求解器求解。
It is shown that these four types of single machine scheduling problems can be modeled as an assignment problem by mathematical programming method , thus these four types of problems can be solved in polynomial time 用數(shù)學(xué)規(guī)劃的方法證明了四類多準(zhǔn)則下的單機(jī)排序問題可以轉(zhuǎn)化為指派問題,從而這四類問題都多項(xiàng)式時間可解。
Secondly , because of the flexibility and complication of the integrated optimization of composite wing structures , there are many difficulties in the design optimization when using the mathematical programming technique 其次,復(fù)合材料翼面結(jié)構(gòu)綜合優(yōu)化設(shè)計靈活且復(fù)雜,它給使用數(shù)學(xué)規(guī)劃方法的設(shè)計優(yōu)化帶來了許多困難。
Founded on the theories of statistical learning , mathematical programming and functional analysis , svr is shown to outperform the traditional multiple linear regression method from the perspective of regression accuracy 根基于統(tǒng)計學(xué)習(xí)、數(shù)學(xué)規(guī)劃及?函分析理論,支援向量?歸方法較傳統(tǒng)的多元?歸方法在?歸正確性上有較好的成效。
Founded on the theories of statistical learning , mathematical programming and functional analysis , svr is shown to outperform the traditional multiple linear regression method from the perspective of regression accuracy 根基于統(tǒng)計學(xué)習(xí)、數(shù)學(xué)規(guī)劃及泛函分析理論,支持矢量回歸方法較常規(guī)的多元回歸方法在回歸正確性上有較好的成效。
Highly abbreviated naming schemes are too common in mathematical programming in my opinion - they make it more difficult than necessary to understand and verify that a mathematical routine works as it should 我的看法是:高度簡寫的命名方案在數(shù)學(xué)編程中很常見,但它們使得理解和證明某個數(shù)學(xué)例程是否按部就班更為困難,而原本不必造成此種困難。
In realistic life and many fields including engineering technology , there exits a lot of uncertainty including stochastic and fuzzy . the uncertainty will bring about great difficulty in making decision for decision maker in mathematical programming 在現(xiàn)實(shí)生活和工程領(lǐng)域中,存在著許多不確定性現(xiàn)象,這種不確定性現(xiàn)象主要表現(xiàn)在兩個方面:一是隨機(jī)性,二是模糊性。
In view of the refinery practice , mathematical programming technique is used to construct the scheduling model , heuristic rules are applied to reduce the constraints and variables number in order to simplify the problem 根據(jù)煉油行業(yè)的實(shí)際情況,用數(shù)學(xué)規(guī)劃方法建立各個功能模塊的調(diào)度模型,運(yùn)用啟發(fā)式規(guī)則降低約束和變量的個數(shù),從而降低問題的復(fù)雜性,是本文采用的一個主要方法。
