Each solver has different capabilities and different levels of performance. For instance, SeDuMi[Stu99], SDPT3[TTT03], and MOSEK support all of the continuous (non-integer) models that CVX itself supports, while Gurobi is more limited, in that it does not support semidefinite constraints; and ...
CVX支持多种求解器,包括SeDuMi、SDPT3、Gurobi和MOSEK等,每个求解器都有不同的功能和性能级别。例如,SeDuMi和SDPT3内置在标准CVX发行版中,支持所有连续(非整数)模型,但SeDuMi速度较快可能不稳定;而Gurobi和MOSEK则支持整数约束,但需要专业许可证。用户可以根据需要使用cvx_solver命令切换求解器。
到此为止,模型的定义已经结束。 其他设置: ① 设置求解精度:cvx_precision default(low/medium/high/best) ② 指定一个求解器:cvx_solver sedumi 本文使用 Zhihu On VSCode 创作并发布 编辑于 2022-09-08 11:05 内容所属专栏 Matlab仿真 LTE协议的Matlab仿真 订阅专栏 ...
该版本的cvx支持4种具有不同特性的解析器slover : SeDuMi、SDPT3、MOSEK 、Gurobi所以使用cvx并不需要去额外下载一个slover,因为CVX的安装包中已经包含了 SeDuMi and SDPT3,这两个slover是免费许可的,默认启用的是SDPT3(The default solver is currently SDPT3)。MOSEK...

I am solving an SOCP problem via CVX. I am trying same problem with different solvers. When I am specifying “cvx_solver sedumi”, the output is “No sensible solution found.” and “Run into numerical problems.”. However, th…
Third, try different solvers. SeDuMi tends to be more effective with the successive approximation method than SDPT3. So if the default solver choice fails to give a solution to your model, try switching to one of these solvers. Third, try smaller instances of your problem. If they succeed ...
在使用MATLAB环境的CVX求解优化问题时,需要调用具体的solver进行求解。而CVX自带的SDPT3和SeDuMi求解器对于包含对数函数,指数函数的目标或约束采用的是连续凸近似方法求解,迭代求解效率较低,比较耗时。而商用的Mosek求解器可以直接求解指数锥约束,对于含有对数函数,指数函数的凸优化问题求解效率更高。CVX中自带的Mosek求解...
