Convex approximations of nonconvex problems provide bounds on the optimal objective value and approximate solutions. The figures below show examples of convex and nonconvex optimization problems.Applications of convex optimization are found in finance and engineering, including portfolio optimization, design ...
第四类是大规模分离非凸优化问题,通过Shapley-Folkman定理证明了当分离项趋于无穷时,对偶间隙趋于零,因此可以求解对偶问题得到原问题的最优解。在通信领域中,这有着重要的应用。最后,奇异值分解(Singular Value Decomposition)及其应用在通信和信号处理中极为关键。通过矩阵的奇异值分解,我们能够以曼若...

Convex Analysis and Nonlinear Optimization 第三章习题解答
书讲的很难,尤其是在没有相应数学基础的情况下,建议先读一读冯德兴老师的《凸分析基础》这本书,它的第一章补充了一些Convex Analysis and Nonlinear Optimization书中第一章中需要用到的知识。但是《凸分析基础》这本书中没有介绍有关矩阵方面的内容,所以本书在阅读时可能还需要查阅一些别的文献。 有用1 没用...

Motivated by aerospace applications, this paper presents a methodology to use second-order cone programming to solve nonconvex optimal control problems. The nonconvexity arises from the presence of concave state inequality constraints and nonlinear terminal equality constraints. The development relies on a...
