Can genetic algorithm help in portfolio optimisation when convexity is not verifiable
I have the following portfolio cost function to maximise:
$$
w^T\mu-\frac{1}{2}\gamma w^T\Sigma w+\frac{1}{6}\gamma^2 w^TM_3(w\otimes w),
$$
which considers the co-skewness ($M_3$ tensor), $γ$ is the ...

How to transform a cubic optimisation problem into a quadratic for portfolio allocation
I have the following cost function for portfolio allocation:
$$
w^T\mu-\frac{1}{2}\gamma w^T\Sigma w+\frac{1}{6}\gamma^2 w^TM_3(w\otimes w),
$$
which considers also the co-skewness ($M_3$ tensor), $\...
