  1. This paper applies generalized multipler method to translate convex quadratic programs with equal constraints and non - negative constraints into simple convex quadratic programs with non - negative constraints. the new algorithm is gotten by solving the simple quadratic program. it avoids the computation of inverse matrix and exploits sparsity structure in the matrix of the quadratic form. the results of numerical experiments show the effectiveness of the algorithm on large scale problems

    根據廣義乘子法的思想，將具有等式約束和非負約束的凸二次規劃問題轉化為只有非負約束的簡單凸二次規劃，通過解簡單凸二次規劃來得到解等式約束和非負約束的凸二次規劃新演算法，新演算法不用求逆矩陣，這樣可充分保持矩陣的稀疏性，用來解大規模稀疏問題.數值結果表明：在微機486 / 33上就能解較大規模的凸二次規劃
  2. Sad is able to differentiate models in form of subroutines, fully exploit the sparsity of the models and need few additional operations. it is concluded that sad is very suitable for the process models that have relatively simple computational structure and consist mainly of polynomials

    符號自動微分具有可對子程序形式的函數求導、可以充分利用模型的稀疏性、無需輔助操作的優點，非常適合針對結構相對簡單、計算式以多項式為主的過程系統模型求導。
