非負二乘解 的英文怎麼說
中文拼音 [fēifùèrchéngjiě]
非負二乘解
英文
nnls-
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D. x. xie, l. zhang and x. y. hu, least - square solutions of inverse eigenvalue probem of bisymmetric matrices, math. numer sinica, 1 ( 1999 ) 62 - 72
