在cvxpy中,DCP规则确保所构建的问题满足凸性要求,从而可以使用内点法等凸优化算法来求解。遵循DCP规则的问题被称为DCP合规问题。 2. 列举可能导致“problem does not follow DCP rules”错误的常见原因 非线性表达式不符合DCP规则:例如,使用了不满足DCP规则的函数(如某些非线性函数)或者对这些函数进行了不当的组合。
I am trying to learn how to multiply power(lmbd,2) with quad_form(z,A) in my objective. I think this part gives error. Error is Problem does not follow DCP rules. objective = cp.Minimize(cp.power(lmbd,2) * cp.quad_form…
Hi, everyone, this problem bothers me for a long time u = cp.Variable((2, 3)) obj = cp.sum(u@u.T) however, the expression of obj is Expression(UNKNOWN, UNKNOWN, ()). But the expression of the obj should be convex, so how should I deal wi...

DCPError: Problem does not follow DCP rules. Specifically: The objective is not DCP. Its following subexpressions are not: ... And then an error I don't undeerstand haha. python cvxpy convex-optimization Share Improve this question asked...
But does one really need a system with such complicated underlying rules to do this? Undoubtedly not. And the situation reminds me of what happened with the problem of ordinary computation universality in cellular automata. Back in the 1950s it seemed one could achieve this with a very complica...
