Linear programming python cvxopt
NettetI want to solve a QCQP in Python. It is a problem from finance: maximise return (linear function) given some linear constraints and one quadratic constraint that turns it into a QCQP. Formally, $$\begin{array}{ll} \text{maximize} & c^T x\\ \text{subject to} & x^T \Sigma x \le \sigma^2\\ & Ax \le b\end{array}$$ Nettet11. sep. 2015 · Python package for large absolute value optimisation.

http://cvxopt.org/documentation/ Nettet20. des. 2024 · I wonder how to use CVXOPT to solve this particular problem. The difficulty I'm having with is twofold. It's not a linear programming and it's not a quadratic either--it's a non-linear programming. Secondly, some of the the large number of constraints are non-linear. In fact, they are cross terms like x1x2>=0, x3x7>=0 and so forth.
