1、在主循环里边,首先把初始值(自己设置的可行解)扔到cvx子程序; 2、cvx输出的变量继续扔到下一次主循环,然后进入第二次子程序cvx。 其实跟很多论文中的伪代码是一样的: 交替变量优化 但实际上CVX里边做不到完全的SCA。cvx子程序里边实际上它自己进行的迭代次数不止一次(而在这过程中使用的都是我们给它扔进去...
If you are maximizing and cvx_optval is -inf, that means the problem is infeasible, which should be reported by CVX Status. Your crude implementation of SCA provides no guarantee that the optimization problems it generates and attempts to solve will be feasible, even if the original non-convex...
非凸优化近年来开始使用无人机对铁路线路,长大桥隧等基础设施及一些维修人员难以进入的区域进行安全监测,特别是在缺乏通信设施的地区,无人机可以为移动用户提供良好的无线通信服务.本文对基于SCA的铁路安全监测用无人机云计算算法的优化研究包括:外部限制条件与优化问题的建模和非凸优化问题的优化两部分,采用CVX库基本...
但是实际你用求解器（如CVX）求解过程中其中一个子问题并没有收敛到全局最优，即不能保证f¯(xk+1...
