I’m trying to solve the following problem:
variable f nonnegative
minimize 256e4.*inv_pos(f) + 1.28e-29.*pow_p(f, 3)
0 <= f;
f <= 2.8e9;
It has a closed form solution with value around 5e8. I tried all different solvers and still get a wrong solutions around 1e4.
This obective function is a part of my original one, so I need to get this part right. Thanks.
