comment Global maximum of non-concave function
Thanks for the answere. Numerically I also found several maxima, too. As you suggest, I want to prove that non of them can be bigger than $f(x_i)$ with $x_i=x_j$. You're right, the cyclic symmetry is notable. Do you have any hint on how to exploit this characteristic?
