In the so-called weighted Dantzig–Wolfe decomposition algorithm, instead of the optimal solution of the Dantzig–Wolfe master problem a specially weighted average of the previously constructed Lagrangian multipliers and the optimal solution of the master problem is used as Lagrangian multiplier for the...
DW分解(Dantzig-Wolfe decomposition)和benders分解 (Dantzig-Wolfe decomposition) 对于标准形式的线性规划,也就是 mincTxs.t.{Ax=bx≥0 如果矩阵A存在一些特点,是有助于我们解决问题的。特别的,如果矩阵形如 矩阵形式 也就是存在大量“整块儿”的零矩阵。在这种情况下问题可以写为 minc1Tx1+c2Tx2s.t.{D1x1+...
•求解大规模优化模型的Dantzig-Wolfe分解算法以线性规划先驱乔治.丹茨格(GeorgeDantzig)和菲利普.沃尔夫(PhilipWolfe)的名字命名,1961年。 •DW分解算法是借助拉格朗日松弛方法,将复杂约束与一个或多个具有易处理的特殊结构的线性约束分解开。 分解得到的子问题通常具备分块对角结构(block-diagonal),分块之间相互独立并...

In this chapter, for convenience in our subsequent discussions in Chapters 4, 5 and 6, the Dantzig-Wolfe decomposition method for large scale linear programming problems with block angular structures is explained in detail. The basic procedure and some of its variants are also introduced.This...
We describe a simple modification of the Dintzig-wolfe decomposition method for nonlinear programming problems, consisting of including an additional column in the master problem, which immediately improves the bound obtained. We investigate the consequences of this modification and can directly give the...
