Witryna7 lis 2024 · 那些熟悉半定规划（SDP）的人知道，在上述关于集合成员关系的讨论中利用集合semidefinite（n）的约束实际上通常用线性矩阵不等式（LMI）表示来表示。例 … WitrynaIn this paper we present an equilibrium value based framework for solving SDPs via the multiplicative weight update method which is different from the one in Kale’s thesis [Kal07]. One of the main advantages of the new framework is that we can guarantee the convertibility from approximate to exact feasibility in a much more general class of …
